Bug 301838

Application: digikam (2.6.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.2
Operating System: Linux 3.4.0-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed: Tried updating to Fedora17 Testing,
 Digikam -2.6.0-1, but still getting an immediate crash after clicking the KDE dialogue to import photos with Digikam.  I was hopeful that this version might not crash.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
