Application: digikam (1.2.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-21-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Before the crash I copied some albums between two different collections (one on an external harddisk, one on the internal harddisk).
This copying tasks ended without problems. Afterwards I selected (clicked) on a different album/folder and Digikam crashed.

The crash does not seem to be reproducible.

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