Summary: showfoto crashes when selecting a filter
Product: showfoto
Version: unspecified
Platform: Gentoo Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: digikam-devel kde org
ReportedBy: cnodes gmail com

Version: 0.4.0 (using KDE KDE 3.5.5)
Installed from: Gentoo Packages
Compiler: i686-pc-linux-gnu-gcc (GCC) 4.1.1 (Gentoo 4.1.1)
OS: Linux

Selecting a filter from the filter menu makes showfoto crash. One filter (I haven't tried every filter) which doesn't result in a crash is 'Distortion Effects ...', but it shows a preview window with no preview.

In digikam everything works fine.

I did a compile with --enable-debug=full configured and a run in gdb resulted in:
...

I hope this makes sense.

It is curious in that the crash only happens with showfoto. Digikam just
works fine.
(And BTW, digikam is definitely the best for image
viewing/processing/management for linux ;-)

I also tried this on a second gentoo machine with the same version of
digikam/showfoto - same problem.

Sure:

This could be important, too:
# grep CFLAGS /etc/make.conf
CFLAGS="-pipe -O2 -march=pentium-m -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}"

For my digikam emerge the USE flags have been
USE="arts kdeenablefinal kdehiddenvisibility xinerama -debug -doc -nfs"
so a typical compile line would be (note the CFLAGS, maybe this is a
problem with -fvisibility=hidden or some other optimization?):

I hope this gives you a hint what could be wrong with my showfoto
compilation. If you need more specific information, please tell me.

I can reproduce it.
Open any image in ShowFoto, open Charcoal effect.

Marcel,

Under Suse and Mandriva, i cannot reproduce the problem using current implementation.

Why the copied DImg instance is null in your computer ? It's a memory allocation problem ?

SVN commit 625731 by mwiesweg:

Fix a linking problem with showfoto, image plugins and --enable-gcc-hidden-visibility:
All image plugins link to libdigikam.so.
The showfoto executable however does not link to this lib, but statically links the relevant parts.
With visibility hidden, now the linker obviously cannot see the already linked DImgInterface class,
and there would be two different static variables for DImgInterface::instance(). One with the loaded
image, the other (from the image plugins) with a null image.
