Thanks for the info. It appears I erroneously assumed from the 08:00:03
timestamp in your OP that it was cron/checkdbs, but it now seems it is
all from your scripts which do not check that the names in
`ls /var/lib/mailman/lists` are all valid lists.

If you would use `/usr/lib/mailman/bin/list_lists -b` instead of
`ls /var/lib/mailman/lists`, you would avoid this problem.

Your code is OK as long as all the names in `ls /var/lib/mailman/lists`
are in fact lists, but it fails when this isn't true.

And yes, the Utils.list_lists() function only returns the names of
directories that contain a config.pck or config.db file.

So, bottom line, use `bin/list_lists -b` instead of `ls lists` to get
the list names, and you won't need to worry about whether or not a
name is a list.
