Bug 275770

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
shutting down system leads to Nepomuk crash.  I literally clicked on the shutdown button and Nepomuk crashed.  No unusual behaviour otherwise.

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