Bug 275818

Application: k3b (1.91.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.34-020634-generic i686
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
DVD had been mounted and folders traversed, when K3b started and "Tools">"Copy Medium" chosen.

At that point the DVD was auto/forced dismounted, and just as the dialogue appeared or was about to appear, K3b crashed and brought up the error reporting wizard.

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