Description James Roe 2012-03-15 06:09:48 UTC 
Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Use the computer for awhile, and when I shutdown (using lancelot), it crashes. It doesn't crash if I shut down quickly after turning the computer on. It's pretty consistent. I'm using Kubuntu 11.10 and KDE 4.7.4 64-bit.

The crash can be reproduced every time.

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