New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.2

- What I was doing when the application crashed:

I walked away to take a leak after just minutes before submitting a bug and here it crashed again. Otherwise system seems fine.

Comment 3 Vishesh Handa 2012-11-02 03:44:54 UTC

Fixed in KDE 4.9

We no longer use the Dbus model for communication.
