Bug 278251

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-0-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
Nepomuk Service Stub seg faults, no specific action an obvious trigger. Seems to happen when the system is heavily loaded, in recent cases when I've been running sound converter converting mp3s...

The crash can be reproduced some of the time.

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