Bug 237708

Application: k3b (1.91.0)
KDE Platform Version: 4.4.2 (KDE 4.4.2) (Compiled from sources)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
K3b crashed when I wanted to burn dvd+r disc, the program pops up a window saying insert a medium, although it is inserted and accepted by linux. When I try to load it again it does nothing, when I retry burning it comes up with same problem.
(I use gnome desktop but k3b burning program.)

The crash can be reproduced some of the time.

 -- Backtrace:
Application: K3b (k3b), signal: Aborted
