OK, done some more reaserching and found this which is very odd:

[root newweb shunt]# su - mailman -c "unset LANG;stat 
/var/lib/mailman/archives/private/depto"
stat: cannot stat `/var/lib/mailman/archives/private/depto': Permission 
denied
[root newweb shunt]# stat /var/lib/mailman/archives/private/depto
  File: `/var/lib/mailman/archives/private/depto'
  Size: 4096            Blocks: 8          IO Block: 4096   directory
Device: 900h/2304d      Inode: 8421391     Links: 35

Now, mailman is the owner, and has all permissions, so why can't he stat 
the directory???
