[Mailman-Users] [Fwd: problem migrating mailman 2.0.8 to 2.1.7]

[apap+mailman-users at auth.gr]

I have trouble upgrading an old installation of mailman-2.0.8 into mailman-2.1.7 (Gentoo Linux with Python 2.4.2).
While installing the new version on top of the old, the "update" utility is invoked, but then it fails with
"AttributeError: topics". No list gets migrated. The same error is produced if I use "withlist" with any old list.

Recreating the lists seems to loose too much user configuration, although it is fairly easy to accomplish.
The system currently serves approx 60 mailing lists.

I found relevant discussions on this list, but not any really helpful answers (yet)
How can I overcome the "AttributeError: topics" error? Is it trivial?
