           Summary: Some pictures make digiKam crash (sample included)
           Product: digikam
           Version: 0.9.0-beta1
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: m.debruijne matrict nl


Version:           0.9.0-beta1 (using KDE KDE 3.5.4)
Installed from:    Gentoo Packages
Compiler:          Portage 2.1.1_pre5 (default-linux/x86/2006.0, gcc-4.1.1/vanilla, glibc-2.4-r3, 2.6.17-gentoo-r1 i686) "-march=athlon-xp -O3 -pipe -fomit-frame-pointer"
OS:                Linux

A friend of mine upgraded digiKam to version 0.9.0-beta1 and since then he cannot start digiKam anymore. We were able to reduce the problem to some pictures. On my system I have upgraded to 0.9.0-beta1 as well and I have the same problem with some of his pictures. We use both exiv2-0.10.

The following error appears when digiKam crashed;
digikam: jpgimage.cpp:317: virtual void Exiv2::JpegBase::readMetadata(): Assertion `sizeIptc' failed.
KCrash: Application 'digikam' crashing...

If you need more information or you want me/us to test something then please let me know.

Thanks!

Michiel,

I can reproduce the problem. I use Exiv2 library implementation from svn and an assertion fault is generarted by Exiv2 in Jpeg image parser just at digiKam startup if your test image have been put in digiKam library path.

Just for information, witch sofware have generated this jpeg image ? Have you included IPTC informations into ?

Andreas, see below the gdb backtrace:

Hi Gilles,

My friend doesn't own a camera. I think he downloaded the picture from the internet so unfortunately I don't know witch sofware have generated this jpeg image. I/he hasn't changed IPTC informations in the picture. I'm sorry I can't give you more information.

Regards,
Michiel.

Thanks for reporting this problem. Pls try the latest Exiv2 revision from SVN. I changed the assertion to a test, which fixes the problem for me. (The image contains multiple Photoshop IPTC IRBs, some are empty and exiv2 doesn't like that.)

This is an interesting picture. It contains all sorts of metadata.

-ahu.

Yes this pictures is very interressing. It have been generated by Photoshop CS from Mac...

With current Exiv2 from svn, digiKam do not crash now. I can close this file...

Andreas,

Perhaps to parse indeep this file from photoshop, we can find a solution about
B.K.O #130525 to store IPTC data over than 64Kb in JPEG ?

Hi Guys,

Thanks for working on this bug! Let's hope a new version of Exiv2 will be released soon so the changes are pushed to the distro's and everybody have a noncrashing digiKam 0.9.0. Do you have a link to svn webinterface or a diff for this change. Can it be applied against Exiv2 0.10? If we need to wait a fair amount of time for the next version of Exiv2 then I can send this patch/diff (and patches for the ebuild) to the Gentoo developers so at least the Gentoo users wont have this problem anymore. Thanks!

Regards,
Michiel.

Michiel,

You have right. The diff to fix this bug is very simple and I think that it can be applied against 0.10.0 release. look here:

http://dev.robotbattle.com/~cvsuser/cgi-bin/ns_viewcvs.cgi/exiv2/trunk/src/jpgimage.cpp?rev=864&view=diff&r1=864&r2=863&p1=trunk/src/jpgimage.cpp&p2=/trunk/src/jpgimage.cpp

I can confirm that the diff works perfectly. Thanks!

For the Gentoo users;
I have created a bugreport with patches for this problem (http://bugs.gentoo.org/show_bug.cgi?id=144347).
