That might fix the problem. Another question worth asking is: have the
resources been set up correctly? The assignment,
pic = QtGui.QPixmap(":/images/triangle.png")
refers to an image in a resource that is usually stored in a module
and imported somewhere in an application before it is used. The image
may reside in images/triangle.png but the original poster needs to
create a .qrc file that lists it, run pyrcc4 on the .qrc file to
generate a Python module, and import that to make it work.
Some of the examples included with PyQt4 use .qrc files to package
images and other resources as Python modules, so there should be
plenty of examples worth looking at.

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.
