-- 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
