I think it's just the usual issue with deleting the children of a QObject. You are creating the dialog as a child of the main window - and therefore transferring ownership of it from Python to C++. In order to delete it then you need to transfer ownership back the other way - see the FAQ. Or you could re-use the dialog each time rather than creating a new one each time.
