error upgrading debconf in debian unstable - python2.2: invalid option -- O

[johan <twilight-zone@mail.ru>]

Hello! I have problems upgrading to debconf 1.3.4. I get the following error 
message:

Setting up debconf (1.3.4) ...
python2.2: invalid option -- O
Try `python2.2 --help' for more information.
dpkg: error processing debconf (--configure):
 subprocess post-installation script returned error exit status 1

It's been like this for a week now, and it causes a lot of trouble because all 
packages that depends on debconf complains that debconf isn't configured yet.

Does anyone else have this problem or am I doing something wrong?
