[PyKDE] PyQt 3.13: crash on exit when using QCanvasSprite

I have a similar problem.

And another one: Sprites just don't ever get deleted.
I am guessing it's because of the reference counting: the QCanvas keeps a
reference, so even if I delete the python object, it doesn't go away.

I could produce a simple testcase if needed.
