Subject: libapache2-mod-python: modpython segfaults when SSL is enabled in Postgresql

Package: libapache2-mod-python
Version: 3.1.3-3
Severity: critical
Justification: breaks the whole system

Hello,

I'm using Python 2.3 with the psycopg1 adaptor and modpython segfaults
when ssl = true is set in postgresql.conf :
[Wed Nov 30 14:32:09 2005] [notice] child pid 11858 exit signal
Segmentation fault (11)
[Wed Nov 30 14:32:11 2005] [notice] child pid 11852 exit signal Aborted
(6)
[Wed Nov 30 14:32:13 2005] [notice] child pid 11861 exit signal
Segmentation fault (11)

I have actually no idea why it segfaults ...
If I connect with ssl to my postgresql server with psql> it works.
If I go on a mod_python page which don't connect to the database with
psycopg it works too ... but if there is a call to the database, it
segfault ...

Here is a strace -f of the process id which segfaults ...
