Application: k3b (2.0.2)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-31-generic i686
Distribution: Ubuntu 13.04

-- Information about the crash:
- What I was doing when the application crashed:
Ripping A DVD that had been recored with Nero
No other user apps were being used.
I have re-tried this four times on two different computers, one with Kubuntu 12.04 OS and the other with Kubuntu 13.04 OS installed.   Crashes occurred in approximately the same place each time... about 35% of the task done.

The crash can be reproduced every time.
