Bug 248908

Application: k3b (2.0.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-24-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
I burned a CD ISO and removed the burned media. After that I closed the DVD tray and K3B crashed. That is all ...

The crash does not seem to be reproducible.

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