Bug 278916

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- Unusual behavior I noticed:

I see this crash when I leave my computer turned on for some hours while I am logged in to the desktop. The process virtuoso-t shows a high CPU load when this happens.

The crash can be reproduced every time.

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