Bug 293123

Application: k3b (2.0.2)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

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

Simply adding .flac files.
Before launching k3b from terminal I also executed:
$ export LC_ALL=C
$ export LANG=en

but this did not help.

The crash can be reproduced every time.

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