Bug 288207

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-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I was trying to launch Scangui from inside Digikam 2.1.1. This behaviour happens each time I try to start Scangui 2.1.1

The crash can be reproduced every time.

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