Application: digikam (1.8.0)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: running Kubuntu 10.10 digiKam crashes on the first two launches in  a session (then usually will run OK).  The splash screen usually says loading kipi-plugins when it crashes.

Thanks for all your great work on this app - one of the real jewels in the  open source crown!

The crash can be reproduced some of the time.

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