Bug 271269

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-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: crash occured when trying to import pictures from Finepix 6500fd. I selected Import-Cameras-USB PTP Camera, then digikam crashed. The same happens to Gwenview. Import via Dolphin works.

The crash can be reproduced every time.

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