rewrote python IDProperty metaclass in C, this was a quick hack to get it working.

The reason this didnt work is all sibclasses of pythons type() or PyType_Type in C, have to have their size set to sizeof(PyHeapTypeObject) rather then sizeof(PyTypeObject) as you might expect.
This is strange since its not a heap-class (defined in pythons runtime), but a static C type, so Im not sure about this, and cant find any documentation but it seems to work ok.
