-- Information about the crash:
- What I was doing when the application crashed:
Added ape file to audio cd project.
When added ogg file first and only afterwards the ape file, the application did not crash but gave an error report about ape format compatibility.

The crash can be reproduced every time.

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