Qt Version: 4.8.3
Operating System: Linux 3.5.0-23-generic i686
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed: Selected new audio project. And browse for folder with mp3 files and also album art images are there too. then right clicked and selected add to project. Adding files diplayed for about two seconds and then, K3b window dissapeared with crash reporting window. Everytime this happened.

The crash can be reproduced every time.
