Is 'append_description.newdescription' the name of a list?
This error occurs when Mailman attempts to read (actually execute) the
optional extend.py module for a list during the instantiation of that
list, and it gets an error exception other than 'doesn't exist'.

/var/lib/mailman/lists/append_description.newdescription is not a
directory. Is it a file?
There should be nothing in /var/lib/mailman/lists/ except
subdirectories corresponding to lists, but Mailman shouldn't really
It's hard to tell without more information, but it looks like this
comes from cron/checkdbs which trys to instantiate every list. It
should only be trying to instantiate lists whose names are the names
of subdirectories of /var/lib/mailman/lists/ and which subdirectories
in turn contain a config.pck file, but something might be wrong with
Mailman.Utils.list_names() (or Mailman.Site.get_listnames() or
Mailman.Utils.list_exists() called by list_names()) that causes it to
return the bogus name.
