Description Kai Denker 2013-05-22 07:46:02 UTC

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

New crash information added by DrKonqi

nepomukservicestub (0.1.0) on KDE Platform 4.10.3 using Qt 4.8.4

- What I was doing when the application crashed:
Using the laptop for usual browsing and email activities. This time happened while shutting down kde.

- Unusual behavior I noticed:
this problem happens randomly, I have yet to find a pattern.
