Application: nepomukservicestub (0.2)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-12-generic x86_64
Distribution: Ubuntu 11.04

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

Installed updates from Ubuntu today.  Running Ubuntu version 11.04 and KDE 4.6.5 (don't know what version I was running before).  These crashes did not occur before this point.

- Running transmission and downloading torrents
- Running Chrome
- Creating disk image using dd ~30GB in size

I can't think of anything else that I was doing that would have an impact.

The crash can be reproduced every time.

-- Backtrace:
