I fell into that too.

The problem is, that even after bin/fixurl is run, the archive directory
/var/lib/mailman/archives/private/ has owner:group = mailman:mailman .
You have to set it to wwwrun:mailman, in order for the apache server to
have write access to it too.
It needs write access for creating lists via webinterface.

This was changed by the last update of mailman via SLES 10 updates,
therefore is a distro bug.

Kind regards,
Christian Mack
