Bug 280604

Application: digikam (2.0.0)
KDE Platform Version: 4.7.00 (4.7.0) "release 10"
Qt Version: 4.7.3
Operating System: Linux 2.6.37.6-0.7-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
importing pictures from camera (canon ixus 980 IS), camera attached to usb or later attaching, when digikam is started, both brings digikam to crash

The crash can be reproduced some of the time.

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