[Mailman-Users] UnpicklingError: unpickling stack underflow

[mjc]

Good morning--

Trying to get to mailman this morning, I get a stack trace


        Traceback:

Traceback (most recent call last):
  File "/var/mailman/scripts/driver", line 87, in run_main
    main()
  File "/var/tmp/mailman-root/var/mailman/Mailman/Cgi/listinfo.py", line 42, in main
  File "/var/tmp/mailman-root/var/mailman/Mailman/Cgi/listinfo.py", line 85, in listinfo_overview

  File "/var/tmp/mailman-root/var/mailman/Mailman/MailList.py", line 546, in __load
UnpicklingError: unpickling stack underflow

I followed the only information I could find and replaced each config.pck 
with config.pck.last, trying to get in after each change.  None of the replacements fixed the
problem and all config.pck 's are now back to the original state.

I don't read python, though I scanned each of the files indicated in the trace. 

Any help would be appreciated
