Bug 288587

Application: k3b (2.0.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Just dragged an entire folder into a new K3b audio cd project.  The folder contains a 'folder.jpg' album art file.  K3b crashed when trying to analyze this file.

The crash can be reproduced every time.

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