mailman broken on 11.1

After upgrading to openSuSE 11.1 mailman fails to send mails and create archives - obviously caused by missing pythonlib/email directory (see [Mailman-Users] AttributeError: Message instance has no attribute’get_type’]( ). I get …

mailman@ara:~> /usr/bin/python -S /usr/lib/mailman/cron/senddigests
List: bonifaz: problem processing /var/lib/mailman/lists/bonifaz/digest.mbox:
Message instance has no attribute ‘get_type’

mailman-2.1.9-159.2 (openSuSE 11.0) had this directory (but simply copying it does not solve the problem). Downgrading to mailman-2.1.9-159.1.x86_64.rpm (from the 11.0 DVD) doesn’t work either.

Any hints how to fix this?

The bug ist tracked in

For the moment I fixed the problem by installing python 2.5.4 and grabbing the
pythonlib/email stuff from mailman-2.1.9-159.2 (openSUSE-11.0).
