New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.6.3 (4.6.3) using Qt 4.7.2

- What I was doing when the application crashed:

I just opened dolphin and nepomuk crashes.
May be it is related to fact that I use plasma desktop with Ubuntu unity.)
But all other attempts to run dolphin are without problems and with running filtering.

nepomukservicestub (0.2) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:

nothing, as KDE session was just open after the gnu/linux boot. Some applications (opera, dolphin, bash, geany and okular were automatically opened at startup).
