Yes. This is a Python 2.6 incompatibility in 2.1.12. It only occurs
when the moderators do the approval because only the moderators are
checking the 'Preserve messages for the site administrator' checkbox
when handling messages. (You might want to check Mailman's spam/
directory to see how many preserved messages are there.)

Here is a patch to fix the incompatibility.
