Application: plasma-desktop (0.3)
KDE Version: 4.3.67 (KDE 4.3.67 (KDE 4.4 >= 20090904)) (Compiled from sources)
Qt Version: 4.6.0
Operating System: Linux 2.6.31-9-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
I was loading the weather forecast plasmoid by adding it from the new plasma widgets browser, i dropped the item onto desktop corona, it proceeded to load then crashed plasma-desktop. It's a Qt 4.6 bug from today's git tree (please forward)
