[Mailman-Users] Problems logging into Admin interface

[Everett Littles]

I have 5 lists on my Mailman server.  Three of the 5 work fine at the 
admin page.  I can log in and administer the lists with no problem.
Two, however, have a problem with the admin page. One of the lists I 
can't log into.  When I log into the list, I get the following error:

Traceback (most recent call last):
   File "/usr/share/mailman/scripts/driver", line 87, in run_main
     main()
   File "/usr/share/mailman/Mailman/Cgi/admindb.py", line 238, in main
     mlist.Save()
   File "/usr/share/mailman/Mailman/MailList.py", line 515, in Save
     self.__save(dict)
   File "/usr/share/mailman/Mailman/MailList.py", line 487, in __save
     os.unlink(fname_last)
OSError: [Errno 22] Invalid argument: 
'/private/var/mailman/lists/llms/config.pck.last'


I ran into this when trying to complete an administrative request.
This same list also sends me the following in email.

At your convenience, visit:

http://http://lists.server.com/mailman/admindb/list1

I have no idea why the double http is being thrown in there.

Can anyone lend some guidance on where to start looking for the root of 
this problem?

Thanks
