Problem with Mailman software and python

Looks like the file which contains the marshalled information is corrupted
somehow.  Look in ListAdmin.py to see what file it's trying to load.  If you
have a recent backup of that machine, restoring that file from backup is
your best bet.  If that's not an option, I have a Python version of the
marshal module here:

    http://manatee.mojam.com/~skip/python/marshalp.py

which instead of raising an exception upon finding an error, returns what it
can.  This may help you recover significant chunks of the file.

(I got this code from Guido a few years ago, then modified it slightly for
this particular task.  It's code he originally wrote so JPython could have a
marshal module.)
