Probably will not help anyway. I stupidly forgot to look in FieldStorage itself.
You are probably just hitting:

        if not ctype.startswith("multipart/"):
            # we don't understand this content-type
            raise apache.SERVER_RETURN, apache.HTTP_NOT_IMPLEMENTED

What is the content type header you are sending contain (exactly)?

If using a basic handler and read() to see what is sent, also dump out
req.headers_in as well.
