The only reason that I can think of for this error message is that the
type of the argument is something that has a repr of
'pylf.core.vector3d', but the type object is not the same as your
'PyType_vector3d' pointer.  As I said, use a source debugger or some
other way to find out, or use a debug build of Python and step through
the PyArg_ParseTuple code to find out why the call fails.
