Are you sure? It should make absolutely no difference.

My experience so far:
1. crashes in call to PySequence_SetItem
2. removed py_DECREF, s/Sequence/List/ -> works OK
3. added code to test return value from PyWhatever_SetItem [you should
*always* test for error], s/Sequence/Object/ -> PyObject_SetItem call
returns -1, PyErr_Print -> "SystemError: null argument to internal
routine"

Looks like a bug or two. I'll rummage a bit more.

Cheers,
John
