[mod_python] mod_python only returns 404 error's

Hi all,

i tried to use mod_python, installation from .deb works fine.

I'm running following configuration:
Apache/2.2.3 (Debian) mod_python/3.2.10 Python/2.4.4c0

then i tried to following skript:

 from mod_python import apache

 def handler(req):
     req.content_type = "text/plain"
     req.write("Hello World! Blarg!")
     return apache.OK


with rights: 755 owned by the suexec user

with the following vhost config:

      AddHandler python-program .py
      PythonHandler mod_python.publisher
      PythonDebug On

when i open the url in browser errlog shows me:
[notice] mod_python: (Re)importing module 'mod_python.publisher'
[notice] [client] Publisher loading page /var/www/test/test2.py

But i got in the browser only a 404 page -  no error's  in log - nothing :(

best regards
