plasma crashed with SIGSEGV while adding/removing/viewing widgets

[Sydney]

Binary package hint: kdebase-workspace

Plasma crashed while I was viewing widgets to place on the desktop. This is Kubuntu Jaunty 9.04 but recently did a 'partial upgrade' and there are new widgets, some of which don't work. Last widget I placed and then removed was PyWeather, I think.

[Apport retracing service (apport)]

Unsetting the need retracing tag, there is no retracer left running on that version of Ubuntu, the crash will need to be manually retraced
