Ooops, something very strange is going on on your system:
chown resolves the group 'users' to gid 100 while 'id -g'
says 1000.
Can you find out why?
Are you using some strange Samba/Kerberos authentication against
an Active Directory or similar? (I've seen such issues with that
combination,)
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".

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