It fails because you initialize gtk.ListStore as if with one column:

        super(PhotoListStore, self).__init__(Photo)

You probably shoud

        super(PhotoListStore, self).__init__(Photo, str, int)

instead.

That non-OOP approach of GTK+ tree models always bugged me as
promoting bad coding style: duplicating data between your real back
end and GTK+ GUI tree model with no means of automatic synchronization.
I actually have some old code lying around, maybe I will try to clean
it up and publish somewhere...

In short, I think this is not easy.  Maybe there are ready-made
solutions out there, e.g. in Kiwi, dunno.
