Bug 289389

Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I cropped or otherwise edited a picture and then I tried to save it, confirmed "overwrite" and the program crashed, repeatedly. Rebooting didn't help. The program crashed upon every "save" command. The actual "save" operation is, however, always successful. I discovered the problem today, haven't got any idea it there was some update of the program recently, I haven't used it for a while.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
