Bug 259336

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I opened the K3b, put a DVD to make a iso-image... the Device Notifier shows the DVD information and BOOM! Crashed the plasma-desktop (hided the panels and the widgets), but everything come back again automaticaly. Perhaps the crash's cause may be the double DVD it's about the WoodStock Festival and the plasma-desktop liked so much... all right, it was a joke to smile a little bit. ;)

Thank You brothers! I love you!
Hugs and Cheers.
