C functions must return an "owned" reference. or in other words, since
Py_None is an existing object, you need to increment the reference count
before returning it:
Py_INCREF(Py_None);
return Py_None;
or, better, but only works in recent Pythons:
Py_RETURN_NONE;
for more on reference counting and object ownership, see:
