Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.2
Qt Version: 4.8.4
Operating System: Linux 3.8.0-22-generic x86_64
Distribution: Ubuntu 13.04

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

I didn't do anything – but the fileindexer was running in the background. After a few minutes of running (it wasn't idle all the time), the nepomukservicestub crashes. Afaics it can only be restarted be relogin, but eventually crashes again.

The crash can be reproduced every time.

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