One way to get around this would be to omit the TreeSortable interface and use TreeModelSort to do the sorting instead. It doesn't look like GenericTreeModel is designed to also support the TreeSortable interface (you would need something like GenericTreeSortable since you would need some magic to allow gobject inheritance from python.)
