Description Barnendu Goswami 2012-01-29 05:57:38 UTC

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: Closed all apps, and chose to shut down (Dell Latitude D630).  This happens everytime when shutting down, but I've found that a restart seems to avoid the crash.

The crash can be reproduced every time.

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