-- Information about the crash:
- What I was doing when the application crashed:
inserted dvd into external usb dvd burner, shell crashed trying to play the movie

- Unusual behavior I noticed:
after a reboot, no longer getting the netbook shell, but the desktop plasma shell instead.,..

The crash can be reproduced every time.

[Comment from a bug triager]
From bug 260778 (4.6 beta2):
- What I was doing when the application crashed:
I had just finished burning two dvd isos (see start of session bug #260772) and
the last dvd was ejecting and reloading so (because my dvd drive locks closed
if no dvd is loaded) I held the tray and changed disks after which it remained
out and the crash occurred.

Comment 5 Lukáš Tinkl 2010-12-28 13:39:23 UTC 
Please try again with KDE 4.6 rc1, thanks
Comment 6 Alex Fiestas 2013-03-12 21:05:41 UTC 
Set as resolved since we have been waiting for info for quite a long time.

Please, if you are able to reproduce this with 4.9.5 or 4.10.1 feel free to reopen it.

Thanks !
