midgard-1.6.3 on debian woody

hi,

I get PHP-errors when loading http://<VHOST>/midgard/
I've put error_reporting(E_ALL) at the top of the cache-file, which shows this:

Warning: Undefined index: session_timeout in /opt/midgard/var/cache/midgard/4-49-8-0.php(239) : eval()'d code(17) : eval()'d code on line 10

In this thread:
http://thread.gmane.org/gmane.comp.web.midgard.user/5117
someone recommended one should downgrade to older aegir because debian-packages
for expat and php are too old. How can I do this?

thanks,
