Some list's lists/LISTNAME/request.pck file is corrupt. Yes, it can be
deleted if you know which one. If you don't, you can try

#!/bin/sh
cd ~mailman       (or whatever)
for list in `bin/list_lists --bare`; do
echo $list
bin/dumpdb lists/$list/request.pck > /dev/null
done

which should throw the same TypeError on the bad file.

Note that this will lose everything that you would have seen on the
list's admindb page were the file not corrupted, but it's basically
lost anyway. If there are held messages, they are in files named
data/heldmsg-LISTNAME-nnn.*. If you want to try to recover these (if
any), see <http://www.msapiro.net/scripts/hold_again>.
