I've noticed a bug in KDE 4.2 which prevents me from adding any widgets to the panel. When I unlock the plasma container on the desktop I'm presented with a window that allows me to add any widget to the desktop as it should, but whenever I try to add a widget to the panel the same window that pops up when adding a widget to the desktop just vanishes. No crash or backtrace appears, the window just draws itself and disappers immediately. Plasma is constantly crashing, this I can live with, but it's annoying when you can't do anything to the panel. Besides aren't the panel and desktop just plasma containers so if one crashes when doing the exact equivalent operation shouldn't the other one crash as well? My distro is Kubuntu 9.04 btw. Has anyone come across this same bug or is it just my installation? I really don't want to delete ~./kde and configure everything to my liking just because of this and hope that it works. I've heard that the proprietary nvidia driver causes problems with KDE 4, but this doesn't sound like a driver issue.
