[mod_python] Publisher Session not functional (?)

Hello, 

I've done some further research and test this code on more configurations: 

#!/usr/bin/env python
# -*- coding: iso-8859-2 -*-
from mod_python import Session

def index(req):
 relace = Session.Session(req)
 req.write(relace.id())


I've tested it on more configurations and Python/mod_python/apache versions, 
but I always get this output (on the end of the mail). 
Is something wrong with the code, configurations or it's bug of 
mod_python.publisher? 

Thanks for any hints,
