Application: nepomukservicestub (0.1.0)
KDE Platform Version: 4.10.00 "release 1" (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.1-default x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: vanilla opensuse beta install and login as root. I was running off a USB flash drive with no swap.

- Unusual behavior I noticed:
nepomuk was using a lot of cpu. restart application button in the crash handler stopped that but thw kde crash handler keeps popping up.

The crash can be reproduced every time.

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