Bug#683815: gdm overrides system's default umask

[email.bug at arcor.de]

Package: gdm

Hello,
in contrast to slim, kdm, or startx, gdm breaks the central
umask configuration.
This is in debian stable (squeeze).

GDM sets the default umask to an explicit value (0022),
however, it should leave it as set by the system's default settings.

(The default umask is set with pam_umask according to http://wiki.debian.org/DebianDesktopHowTo)

Executed in an xterm called directly from ~/.xsession
~$ umask
0022

while a text console gives a correct:
~$ umask
0002
(as set by pam_umask.so usergroups)
