New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.6.4 (4.6.4) "release 8" using Qt 4.7.3

- What I was doing when the application crashed:

Browsing the web on Firefox, transferring files to cellphone via bluetooth, running soundKonverter so processor use was very high
