Application: gwenview (2.6.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Each time when I open certain folders in Gwenview and the application is generating thumbnails, the crash occurs. It also happens when opening certain image files directly with Gwenview from Dolphin.
Opening the files in GIMP and saving them again, solves the problem for these files.

The crash can be reproduced every time.

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