Bug 308640

Application: gwenview (2.8.5)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-32-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Rename png file with F2 and enter new filename. Accept with enter.
Hit F5 to see the filename changed -> crash. 

Tried twice, crashed both times.

The crash can be reproduced every time.

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