Thanks for the quick reply - this is a strange old server (not my doing...).
Indeed it uses an external authentication, and has conflicting local and 
global groups named "users".

==
$ grep users /etc/group
users:x:100:
$ getent group | grep ^users
users:x:100:
users:x:1000:
$ id -G
1000 1001 3432

So I guess this is not a bug, and can be closed.
I'll just ignore this failure on this system.

Thanks,
