[Bug 200159] New: Digikam almost always crash on my system (trunk)

[Alex Fiestas]

https://bugs.kde.org/show_bug.cgi?id=200159

           Summary: Digikam almost always crash on my system (trunk)
           Product: digikam
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Application that crashed: digikam
Version of the application: 1.0.0-beta3 (rev.: 996173)
KDE Version: 4.3.60 (KDE 4.3.60 (KDE 4.4 >= 20090706))
Qt Version: 4.5.1
Operating System: Linux 2.6.30-ARCH x86_64

What I was doing when the application crashed:
Since I upgrade to kde 4.3 (I'm in trunk right now) digikam almost always crash
at startup, showfoto some times crash too with so similar bt.

I don't know what exactly is failing, I've tried removing configurations etc,
but the bug is persistent.

Thanks and great job!

Not good so :/
I'm using ArchLinux with testing repo, maybe it helps to be able to reproduce
it.
I'll try to install a clean archlinux+testing+kdemod and see what happens.

Thanks for the quickly response!

Gilles this reminds me of these crashes lately that were caused by setting a
special environment variable for malloc. Dont find the bug numbers right now. I
think we closed the reports somehow.

This crash now comes from the JPEGlossless plugin. If you have always this
backtrace there may be a problem with the installed kipiplugins package.
If the backtrace is different for each crash, there is a more general problem.

Please note that you are running unstable trunk KDE4.4 alpha. It may be worth
to install a stable KDE4.3rc2.

Wow! finally I can continue with my photos collection! thanks!

Ps:JPEGlossless is crashing my digikam also in a kde 4.3rc1 system, should I
report a bug?

Thanks!

To the bug reporter:  I see you're using a x86_64 system.  Do you have glibc
2.10.1 installed (you can tell by running /lib/libc.so.6 at a terminal and
checking the version output on the first line)?

If you do, I think you are experiencing bug 196207.  If this the case you can
confirm by testing any of the following workarounds:

At the terminal before running digikam, run "unset MALLOC_CHECK_" (without the
quotes, and note the trailing underscore).

Or, at the terminal before running digikam, run "export QT_NO_GLIB=1" to
disable the glib-based Qt event loop and use a native Qt event loop instead.
If you can't reproduce this crash after taking either of those steps you're
probably seeing what I believe to be a glibc bug (one I haven't found a
reproducable simple test case for :( )

I can not crash digiKam with KDE 4.2.4 and MALLOC_CHECK_=3, so I guess it is
"save" to say that the JPEGLossLess-plugin is not causing the crash, but either
kdelibs or glibc.

Alex, I got your jpeglossless plugin too after updating kdegraphics/libs.
Solution was to update kipi-plugins as well.

Ok now I have this crash, too.
I updated to a package bugfix release (KDE 4.2.4-2) and now I can't start
digiKam anymore.
I rebuild all libs (from trunk) and kipiplugins as well as digiKam, but it is
not working.

Since your backtrace is not valid anymore (I can't see the link), I'll post
mine here:

The only thing to solve this is to remove JPEGLossLess.

Gilles,

while removing this plugin I have found a "bug": we don't disable the overlay
icons in iconview.
So if KIPIplugins are not installed at all, the user will still see the rotate
icons which is wrong I guess.

Andi,

Right i can see the problem in code about jpeglossless avaibility and overlay
icons. To deal with plugin action in icon view is not trivial

I think to use JPEGLossless plugin here is a wrong way. In fact I think we must
to disable this plugin in digiKam and make a dedicated code in digiKam core. We
have lossless jpeg code in core (used by camera gui). For non JPEG format, we
can use DImg as well.

Also, in BQM, Rotation tool don't take a care about lossless jpeg
transformations. It's weird. Implementing a solution in digiKam core will solve
this issue.

I guess my problem with JpegLossLess comes from the upgrade of libjpeg (6b-6 ->
7-1).

A lot of applications seems to crash now, because it is not ABI compatible (not
even API, although it should).

Recompiling worked for me as I said before, but unfortunately it crashes with
the above backtrace.
I'm pretty sure that this upgrade is causing the issue.

look changes there :

CHANGE LOG for Independent JPEG Group's JPEG software


Version 7  27-Jun-2009
----------------------

New scaled DCTs implemented.
djpeg now supports scalings N/8 with all N from 1 to 16.
cjpeg now supports scalings 8/N with all N from 1 to 16.
Scaled DCTs with size larger than 8 are now also used for resolving the
common 2x2 chroma subsampling case without additional spatial resampling.
Separate spatial resampling for those kind of files is now only necessary
for N>8 scaling cases.
Furthermore, separate scaled DCT functions are provided for direct resolving
of the common asymmetric subsampling cases (2x1 and 1x2) without additional
spatial resampling.

cjpeg -quality option has been extended for support of separate quality
settings for luminance and chrominance (or in general, for every provided
quantization table slot).
New API function jpeg_default_qtables() and q_scale_factor array in library.

Added -nosmooth option to cjpeg, complementary to djpeg.
New variable "do_fancy_downsampling" in library, complement to fancy
upsampling.  Fancy upsampling now uses direct DCT scaling with sizes
larger than 8.  The old method is not reversible and has been removed.

Support arithmetic entropy encoding and decoding.
Added files jaricom.c, jcarith.c, jdarith.c.

Straighten the file structure:
Removed files jidctred.c, jcphuff.c, jchuff.h, jdphuff.c, jdhuff.h.

jpegtran has a new "lossless" cropping feature.

Implement -perfect option in jpegtran, new API function
jtransform_perfect_transform() in transupp. (DP 204_perfect.dpatch)

Better error messages for jpegtran fopen failure.
(DP 203_jpegtran_errmsg.dpatch)

Fix byte order issue with 16bit PPM/PGM files in rdppm.c/wrppm.c:
according to Netpbm, the de facto standard implementation of the PNM formats,
the most significant byte is first. (DP 203_rdppm.dpatch)

Add -raw option to rdjpgcom not to mangle the output.
(DP 205_rdjpgcom_raw.dpatch)

Make rdjpgcom locale aware. (DP 201_rdjpgcom_locale.dpatch)

Add extern "C" to jpeglib.h.
This avoids the need to put extern "C" { ... } around #include "jpeglib.h"
in your C++ application.  Defining the symbol DONT_USE_EXTERN_C in the
configuration prevents this. (DP 202_jpeglib.h_c++.dpatch)

// ---------------------------------------------------------------------

we MUST take a care about transupp.c code in digiKam core and JPEGLossless
plugin. There is a risk to see jpeg transformations broken. Code stil
compilation and run perfectly on your computer ?

Like I said, JPEGLossLess is not starting at all and crashes digiKam.
digiKam seems to work ok, I tested "Perspective Adjustment" right now, if this
is handled by the lib?

So at the moment I see only problems with JPEGLossLess. It compiles, but
doesn't run.

No perspective tool do not use it.

Only these parts:

- DImg jpeg loader,
- rotation tool from cameragui (libs/jpegutils)
- jpeglossless plugin.
