There's your problem: The model is garbage collected at the end of
__init__. The table view's setModel function does not increment the
refcount on the model!

I don't have a copy of the PyQt4 doc's at hand, but if this is not
stated on the first page, Phil should probably add it.

I fell into this trap too, a couple of times..
