Bug 314934

Application: k3b (2.0.2)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic x86_64
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:
I was going to rip a dvd when I was notified that extra packages could be installed.  I installed the MP3 package and then K3B crashed when trying to rip the dvd.

K3B now continually prompts to install the MP3 package.

The crash can be reproduced every time.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
