Segmentation fault

dear list members

i have the python code below (from initialize.py) to test ldap 
connection over ssh to an external ldap-server.

on my production system with python-2.1.3, python-ldap-2.0.0pre06, 
openldap-2.1.12, openssl-0.9.7c i get a correct output. but when using 
my development system with python-2.1.3, python-ldap-2.0.0pre19, 
openldap-2.1.23, openssl-0.9.7c i get a segmentation fault:

*** ldaps://x.x.xx:636 - SimpleLDAPObject.set_option ((17, 3),{})
*** ldaps://x.x.xx:636 - SimpleLDAPObject.set_option ((17, 3),{})

can anybody tell me how to solve this? i don't think that this can be 
ignored. i guess that this is also the cause for my problems with the 
latest LDAPUserFolder which i wanted to use with zope.

thanks in advance for any hints.
regards,
marc
