Well, downstream we have the complete() call.  Try changing the return section 
  to:

                 try:
                     print 'comp:<%s>' % 
self.matches[state].replace(magic_prefix,magic_escape)
                     return self.matches[state].replace(magic_prefix,magic_escape)
                 except IndexError:
                     return None

And see how that fares.  Use this bracketed <%s> print to make sure you see 
_exactly_ what is being returned, with specifically marked endpoints.
