QAbstractItemModel.parent(QModelIndex) overloads QObject.parent(), so it 
is a bug in PyQt4/5 that it doesn't support the latter.

That doesn't explain what is wrong with the code though. The problem 
there is the same as the other example the OP posted, and has the same 
kinds of solutions (e.g. give the model a parent, or use 
sip.setdestroyonexit(False)).
