Bug 277874

Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-0-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Using K3B to rip audio CDs to mp3.  Nempomuk crashes a few minutes into the rip.  If restarted, it crashes on the next disk.

The crash can be reproduced every time.

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