Bug#731686: gdm3: poweroff/reboot seems to be a noop

[Steven Post]

Package: gdm3
Version: 3.8.4-6
Severity: normal

Dear Maintainer,

When trying to reboot from inside the gdm3 login screen, nothing appears to
happen. After several tries I can still login to Gnome and poweroff/reboot from
there.
Switching to a tty and rebooting from there also works.

This problem appeared after the upgrade to 3.8, no reboot ever worked from the
3.8 screen, but it worked in 3.4.

Best regards,
Steven
