Application: gwenview (2.5.0)
KDE Platform Version: 4.4.90 (KDE 4.4.90 (KDE 4.5 RC1)) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

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

I opened a file through Dolphin, hit esc (out of habit, I actually wanted to close Gwenview), this dropped me back to the directory view. Then I closed Gwenview and it crashed.

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