How does it fail?  Raises an exception?  What is the actual exception
type and value?  It sounds strange to me cuz I've never had to worry
about null bytes in strings in my Python travels.

Dumb questions maybe, but what handler are you using?  If you're using
the publisher handler, then maybe that zero at the end is what
apache.OK equals?
