New crash information added by DrKonqi

nepomukservicestub (0.2) on KDE Platform 4.6.4 (4.6.4) using Qt 4.7.2

- What I was doing when the application crashed:

I was shutting down my machine and during the shutdown process this crash occurred.  I had been using KMail/Kontact extensively, and it had hung while making IMAP connections numerous times requiring me to kill Kontact/KMail a couple of times to be able to start it again.

-- Backtrace (Reduced):
