Bug 278669

Application: gwenview (2.5.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I was rotating images. Perhaps too many at one time?  But I usually get a message that memory is running low and I should save my work. I use this on a Gnome desktop. (This is not in the summary)

The crash can be reproduced some of the time.

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