You probably shouldn't store the actual QModelIndex objects. From memory
(and bearing in mind that it's very late here) there's a way to pass in a
Python object when your model creates indexes and get them back again later.
Ideally, this is what you should do.

I tried running your test case and found that the view displayed various
items in an incomplete way - when you see trailing branches, it's a sure
sign that something isn't quite right.
I'll try and take a look at this tomorrow unless someone manages to help
you out in the meantime.
