[Mailman-Users] can't get into admin

[Merrill Cook]

This bug report with v 1.0 is getting really annoying. It has been
somewhat intermittent, but seems now to be more and more common. It
happens when trying to get to the admin page for some of our lists. This
is as far as it gets.

The funny thing is that this machine is referenced under two domain
names; when we use the other domain name, we do not have this problem.
The list was set up and mostly works fine with the first domain name.
The second domain name (the one that works with this script) is used for
some scripts, and the program seems to be fine (mail aliases work, web
server works, etc.).

Any ideas?
