Application: gwenview (2.8.1)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
I openened an arbitrary jpeg image in Gwenview (by double-clicking it in Dolphin), switched to fullscreen mode (double-click on the image), used the thumb bar to leaf through the available images in the same folder.
More often than not, Gwenview would crash once I came to a particular image.
If I opened that image directly, no crash would occur.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
