-- 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
