It looks like this might be an actual bug. There is an incompatibility
between Mailman 2.1.12 and Python 2.6.x in this area, but not right
there. At lines 205 and 254 in your version of ListAdmin.py, g(msg, 1)
needs to be changed to g.flatten(msg, 1). However, that doesn't cause
what you're seeing.
Do you have
HOLD_MESSAGES_AS_PICKLES = No
in mm_cfg.py. If so, I think there is a bug with this. Unfortunately,
I'm traveling this week and it will take be a while to investigate/fix this.
In the mean time, if that is the issue, you can remove that from
mm_cfg.py if you don't need it for other reasons.

That is a mail-archive.com issue. You could search Google for
inurl:mailman-users site:mail.python.org "We're sorry, we hit a bug!"
but that returns over 5000 hits, most if not all of which are not
relevant. It's much better to search with something like
inurl:mailman-users site:mail.python.org "ValueError: could not convert
string to float"
which returns only 8 hits, including a couple from 2003 and 2004 which
indicate this is an old bug.
