Bug 280927

Application: digikam (2.0.0)
KDE Platform Version: 4.7.00 (4.7.0) "release 10"
Qt Version: 4.7.3
Operating System: Linux 3.0.3-2-default i686
Distribution: "openSUSE 11.4 (i586)"

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

I was trying to download new pictures from a camera (Canon IXUS 80IS). Digikam Splash was visible, different mdules has been loaded. 
Then suddenly digikam crashed. I did not meet this problem in former versions (same camera).

The crash can be reproduced every time.

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