There is a full Python traceback from this error. That will help if rhe

The problem is the listinfo overview (and probably the admin overview
has the same issue) has to instantiate every list in the installation
to determine whether or not it should be shown on the overview page,
and something is wrong with the lists/listname/config.pck for one of
those lists.

Make the following two line file

def no_op(mlist, *args):

and save it in Mailman's bin/ directory as no_op.py. Then run

bin/withlist -a -r no_op

That should produce output similar to

Importing no_op...
Running no_op.no_op()...
Loading list century-announce (unlocked)
Loading list century-announce-test (unlocked)
Loading list list1 (unlocked)
Loading list mailman (unlocked)
Loading list test (unlocked)

Except with your installations list names, and except that at some
point there will be an exception and a traceback. The last

Loading list listname (unlocked)

before the error is the one with the bad config.pck. You might just try
removing the config.pck and letting Mailman fall back to
config.pck.last. If that doesn't work, you can resort to a backup if
you have one.
