Bug 286976

Application: k3b (2.0.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Title describes it all - it happens every time. What's strange is that it doesn't happen with all my .wma files, only some. The ones that don't crash K3b cause it to let me know that K3b can't handle (at least not be default) .wma format. The .wma files that do crash it might have some issues themselves - I can't seek in them, but they play through all the way just fine.

Either way, it's not an ideal situation on my part, but I thought I'd report this anyway since no one wants a crash, regardless of the reason. I'm using ffmpeg version 4:0.7.2-1ubuntu1. Let me know if you want me to attach or upload a .wma file that cause a crash. Cheers.

The crash can be reproduced every time.

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