There have been some related discussions on the mailing list you might take a look at, for instance: http://www.riverbankcomputing.com/pipermail/pyqt/2006-July/thread.html#13786. Google [ site:riverbankcomputing.com internalpointer ] to find some more. It might also be interesting to rewrite your Python code in the corresponding C++ and see if you see similar behavior. In my limited use of proxy models, I have not found it useful to store QModelIndex objects in the internalPointer(). Instead I have created some "proxy data objects" that reference the actual data model (which is Qt-independent). I subclassed QSortFilterProxyModel since it implemented a bunch of stuff I would otherwise have had to reimplement. I would also note that your proxy model did not implement mapToSource() and mapFromSource() as required, though I don't think they would be called in the simple example you posted.
