Application: digikam (3.1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-41-generic-pae i686
Distribution: Ubuntu 12.04.2 LTS

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

DigiKam crashed when I was applying the correction to the second picture. Always when I'm using this function it works properly with the first picture I choose. But using this function a second time leads always to a crash of digikam.
Nevertheless: I like digikam and I'm happy about the progress you made!

The crash can be reproduced every time.

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