Comment 2 for bug 546781

I can confirm this. I tested it with a fresh lucid install and two updated ones (from karmic). The 2.2 package from universe always crashes the whole plasma desktop when the settings of the widget are closed, no matter if you have the widget on the desktop or in the panel. I too have compiled 2.2 from sources and it works fine, it's just the universe package that seems to be faulty.
