Well, I *do not* confirm this.

Window 1:

root@mykerinos:~# su - tintin
tintin@mykerinos:~$ id
uid=3D1000(tintin) gid=3D100(users) groups=3D100(users)
tintin@mykerinos:~$ newgrp audio
Password:
Sorry.
tintin@mykerinos:~$     =20


I do NOT logout from this shell and in anothe window (window 2):

root@mykerinos:/etc/pam.d# addgroup herge
Adding group `herge' (1006)...
Fait.
root@mykerinos:/etc/pam.d# adduser tintin herge
Ajout de l'utilisateur tintin au groupe herge...
Fait.



Going back to "tintin" shell in window 1:

tintin@mykerinos:~$ newgrp herge
tintin@mykerinos:~$ id
uid=3D1000(tintin) gid=3D1006(herge) groups=3D100(users),1006(herge)
tintin@mykerinos:~$ touch foo
tintin@mykerinos:~$ ls -la foo
-rw-r--r--  1 tintin herge 0 Mar 31 07:47 foo


So, where's the bug?
