In pylibs.py, there is a comment that says:

#handle_starttag is never called!

In accordance with the comment, there is no definition for
handle_starttag. There is a (seemingly correct) definition for
unknown_starttag but it doesn't seem to ever get called. This seems to
fix it:

def handle_starttag( self, tag, method, attributes ):
    self.unknown_startag( tag, attributes )

I don't know why that wasn't in to begin with. The mysterious comment
probably has something to do with it.
