Application: digikam (2.3.0)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu oneiric (development branch)

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

Final step of stitching a panorama (3 or 13 raw images).

After the wizard asks if it should do auto leveling and auto-cropping it crashes.

Happens every time

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Aborted
