[Mailman-Users] broken List-archive header

[Joel Uckelman]

Yesterday I upgraded Mailman to 2.1 and started to notice the following 
problem: The List-archive headers in messages coming from my lists all look 
like this:

List-archive: </archives>

while before they looked like this, e.g.:

List-archive: <http://lists.ellipsis.cx/archives/hosers-talk/>

What's happening to the rest of the URL?

I have PUBLIC_ARCHIVE_URL set to 'http://lists.ellipsis.cx/archives/%(listna
me)s/', and it *is* showing up correctly in the archive links on the list 
info pages.

Any ideas?
