Application: digikam (1.3.0)
KDE Platform Version: 4.4.92 (KDE 4.4.92 (KDE 4.5 RC2))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

It keeps occuring:  I am viewing the photos in an album, pressing space/backspace to move through, and the application just disappears.  No photos seem to be affected.

The crash can be reproduced every time.

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