Bug 282744

Application: digikam (2.1.1)
KDE Platform Version: 4.7.1 (4.7.1)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-11-generic i686
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Hit "Import from USB device" immediately after starting digiKam. First, files show up, then digiKam starts processing thumbnails, then it crashes.

Notes:
1. I re-installed fresh digiKam after apt-get -u --purge remove 'digikam*'
2. The phone is up-to-date HTC Evo 4G.

The crash can be reproduced every time.

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