Bug 271046

Application: digikam (2.0.0-beta4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64
Distribution: Linux Mint 10 KDE

-- Information about the crash:
- What I was doing when the application crashed:
Attached camera via mini-USB, observed camera appear in 'Devices' system tray and selected 'Download Photos with Digikam' from possible actions. Digikam started, atttempted to download from the camera and then crashed. This is repeatable.

The crash can be reproduced every time.

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