[PyQt] Annoying TypeError with graphics animations

[B. B.]

Hello all,

I get some strange TypeErrors when I use the QGraphicsItemAnimation.

An example can be boiled down to the example below taken from the Qt
documentation :
http://doc.trolltech.com/4.5/qgraphicsitemanimation.html

What I get is this error, when the application is running.

"TypeError: native Qt signal is not callable"

I have installed the snapshot : PyQt-x11-gpl-4.5-snapshot-20090403.tar.gz
under python2.6 ( verified the error under python2.5 too )

I can hardly see that I do something wrong.. or is it my installation that
has failed??


best Regards

BBZ
