[Pkg-utopia-maintainers] Bug#799890: policykit-1: Shutdown/reboot requires authentication

[Gedalya]

Between November 29 and 30 I got policykit-1 0.105-14, systemd 228-2, 
lightdm 1.16.6-1.
After a full reboot, the issue is gone. Just logging out didn't help.
I only realized now since I hadn't had a chance to reboot any machine in 
the mean time.
My guess is the fix is in one of these 3 packages, no concrete evidence.
