Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Every time I login to KDE nepomuk crashes immediately.  It seems to work just fine after I click the restart button in the crash dialog.

The crash can be reproduced every time.
