Did you try an empty string for the selector?
This is a bug, in any case. None for a selector should pass NULL to
the underlying method.
We are now using the pyobjc.sf.net bug tracker, btw... and it *should*
be sending bug reports to this list or pyobjc-checkins [can't remember
which it was set up for].
