Operating System: Linux 2.6.34.6-54.fc13.x86_64 x86_64

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

Nepomuk working in the background as normal and crashed. Does it from time to time, esp since I updated to kdelibs 4.5.1

The crash can be reproduced some of the time.
