Thanks for the clues, I made a modification so that reduce returns this..
return Py_BuildValue("O(OOOOO)", Py_TYPE(self), PyTuple_New(0), Py_None,
Py_None, Py_None );
and now I get this different error when trying to pickle the type..

You need to do two things:
1. Set tp_name to something like "mymodule.MV" where "mymodule" is the name of
your extension module.
2. Make sure that you add the type object to your module's namespace.
PyMODINIT_FUNC
initmymodule(void) {
...
Py_INCREF(&PyMV_Type);
PyModule_AddObject(m, "MV", (PyObject*)&PyMV_Type);
}
C.f.
