[mod_python] mod_python stops Apache

Hi,
I'm running FreeBSD 5.3-BETA and Apache2 and mod_python 3.1.3, all
installed from ports. All I've added to httpd.conf is:

LoadModule python_module libexec/apache2/mod_python.so
AddHandler python-program .py
PythonDebug On

When Apache starts, it sais:
[Tue Sep 07 08:50:16 2004] [notice] mod_python: Creating 32 session
mutexes based on 150 max processes and 0 max threads.

and then it quits with error-code 0 and no core dumps. What's happening?
How can I keep Python living? If I keep only the LoadModule statement, it
still quits. Without the statement, Apache runs smooth as usual.

Cheers

  Nik
