Description kdebugsuser 2014-04-14 10:52:30 UTC

Application: digikam (3.5.0)
KDE Platform Version: 4.12.3
Qt Version: 4.8.5
Operating System: Linux 3.13.9-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
started digikam. no further user-interaction.

- Custom settings of the application:
digikam is configured to use mysql. digikam was scanning files from a cifs-mount. 

bug seems to be reproduceable. is there a way to get the filename of the image, which was loaded while crashing?

Fedora 20 guest on kvm. stable hardware (ECC).
MAYBE related to http://retrace.fedoraproject.org/faf/problems/1453645/

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

Comment 3 kdebugsuser 2014-04-15 22:10:33 UTC

I am using qt version 4.8.5-15.fc20.
A bug-report was filed today: https://bugreports.qt-project.org/browse/QTBUG-38367

Is there any way to get the filename of the gif-File ?

Comment 4 Christoph Feck 2014-04-18 02:22:52 UTC

You could use the "strace" command in Konsole to find out which files digikam tries to open before it crashes. On the other hand, GIF is a pretty rare format nowadays, so a simple "find | grep -i gif$" might help, too.

Comment 5 kdebugsuser 2014-04-27 22:15:49 UTC

Thank you Christoph. There were many gif-files and I finally tracked the problem down by simply searching for the decode-buffer-parameter-string in all gif-files. But I really wish digikam would provide better logging. After removing the gif-file, I got digikam to scan all files. But I never managed to create the thumbnails.

Comment 6 kdebugsuser 2014-04-27 22:26:46 UTC

I reported this bug to the qt-Security-Team. They fixed it.
CVE-2014-0190:
http://lists.qt-project.org/pipermail/announce/2014-April/000045.html
https://qt.gitorious.org/qt/qtbase/commit/eb1325047f2697d24e93ebaf924900affc876bc1

So I guess this bug can be closed.

Comment 7 Christoph Feck 2014-04-27 22:49:58 UTC

Thanks for the heads up! Closing.
