Bug 201792

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.98 (KDE 4.2.98 (KDE 4.3 RC3))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
When I open "Desktop Settings" and chose the "Globe" wallpaper type the screen immediately goes black (even before the UI updates to show the Globe options and before I can select Apply) and then plasma restarts.

The first time I chose the globe (yesterday) it worked and I could interact with its configuration UI, and it did update the desktop wallpaper.  At the time I decided against using it... now I can't seem to revert this decision.

This is a vanilla Kubuntu 9.04 Jaunty Jackalope updated to KDE 4.3 RC1 from the "official" PPA on Launchpad.
