Bug 221593

Application: k3b (1.68.0)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
In attempting to burn an iso k3b will sometimes state K3b does not have permission to write to this device. Sometimes repeating the process effects a burn sometimes slowing the burn speed instead of using automatic choice. Sometimes restarting the system will work.

The crash can be reproduced some of the times.

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