Application that crashed: k3b
Version of the application: 1.68.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I made a burn project from usb stick. Perhaps the project was made from hard disk from directory which have deleted afterwards. The K3B have list of medium on left side of user interface. When I clicked with mouse the media, which had disappeared, K3B made a segmentation fault.

I think that the program should check if the media is available and if not, it should handle that case ok.
