Bug 267674

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.38-020638rc7-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

open dolphin, nepomukstub storage instantly crashes.

usually when i restart nepomuk it wont crash everytime, its kinda random.

The crash can be reproduced every time.

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