I had opened the application and had just selected a file to burn when the application crashed.  This has happened to me many times in spite of having reinstalled the application.

The crash can be reproduced every time.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
