Bug 270654

Application: digikam (2.0.0-beta4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

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

Digikam Crashes when during Configuration You Select Settings, Configure, Camera,  Then as soon as you choose Camera the application immediately crashes without fail each and every occasion.

It is impossible to add anything at this point.

The crash can be reproduced every time.

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