Bug 281042

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0.0-9-generic x86_64
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Nothing special. Icon in systray flashing a  few hours (appear and disappear), after that crash assistant brings me this surprise.
Stack trace differs from proposed duplicates, something related to D-Bus.
Sorry if it really dup.

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