Bug 274075

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: Running Firefox (x4 Windows), KMPlayer, Dolphin, Kate, Amarok, and Kopete. dbus service found to be using 100% cpu mid-way through a movie with KMPlayer. Force-close of dbus service.

- Unusual behavior I noticed: Computer running/responding slowly. Investigation revealed dbus causing issue. Killed process immediately.

Bit of a noob here. Hope this helps.

-- Backtrace:
Application: Nepomuk Service Stub (nepomukservicestub), signal: Aborted
