I've tested all the codepaths now, by...

Implementing the changes in taskbar. They ended up being even less than
I thought and uncovered two bugs in plasma in the meantime (which I've
checked in). I've reattached the widget patch against current subversion
as well as the changes needed for tasks.

If Plasma::View notifies Plasma::Corona that then notifies its containment(s?)
about changes to the Plasma::View's geometry, this widget patch could address 
the above issue as well with very little overhead. I should stop overloading
the meaning of QGraphicsItem::ItemPositionHasChanged and give this a try...
