[mod_python] mod_python with xmlrplib

I haven't been able to use xmlrpclib with mod_python.
When I import xmlrpclib the apache server crash (segmentation fault),
the following code will be show it.

=====================================
from mod_python import apache
import xmlrpclib

def handler( req ):
         req.write("Hello World!")
         return apache.OK
=====================================

My system:
   RedHat ES 3
   Apache 2.0.52
   Python 2.4

Is there a way to fix it?

Thanks
