Thanks for your hints,

in fact the problem has been solved yesterday...
My scene was refering to nothing at all, add a "self" like this :

scene = QtGui.QGraphicsScene(self)

and the image appears.

Now, Dave just told me it was a bad idea to put an image on a 
QGraphicsView. I've already done it inside a Label, but I've no controls 
on it. He suggested I've to write my own widget (from Qlabel or QWidget) 
for that, but I don't see why it's a bad design decision.

David : thanks again for your good work on the wiki.
