Description Andrei Nistor 2010-08-31 14:55:29 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.6.3
Operating System: Linux 2.6.33-CHAKRA x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I logged out, and just after logging back in nepomuk crashed.

- Unusual behavior I noticed:
I logged out because X started to use 100% CPU out of a sudden, don't know if it's related, I've been having issues with it since a while ago.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
