Bug 272278

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.00 (4.6.0) "release 6"
Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.5-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:Nepomuk crashed after cliking Search Button in Dolphin, just happend once... will try again.  But this kind of crashes appears to happen ramdomly not just with Nepomuk module.
I am sure that if I try the same thing the crash wil not happen again.

The crash can be reproduced some of the time.

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