Bug 306792

Application: gwenview (2.9.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.2
Operating System: Linux 3.2.0-31-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I selected an image (tiff) in Krusader (Version 2.4.0-beta1 "Migration"), then I choosed "Open with Gwenview". Gwenvies opened teh image file as usual. I went to the menue "modules" and there to "resize". Suddenly Gwenview crashed to desktop! digikam 2.6 was running in the background.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
