Bug#440955: gnome-screensaver: fails with pam_unix2

[Marcos Pinto]

Package: gnome-screensaver
Severity: grave
Justification: renders package unusable

when using pam_unix2 for better security, gnome-screensaver fails
to unlock and always reports an invalid password.  this is because
/etc/shadow is "-rw-r----- 1 root shadow" and gnome-screensaver
is not in the shadow group by default and apparently cant read
the file
