potential bug report for gdm

specs:
* Stock Ubuntu Gnome 14.04

what happened:
* I have two users: 1 admin, 1 normal.
* AutomaticLoginEnable=True at first, but then disabled through GUI.
* Reboot
* Now admin user requires password as expected, but
* User choice has a progress bar and logs me in after it finishes loading

whad is expected:
* I should not be logged in automatically after a time delay
  as I explicitly disabled auto login

how to fix it:
* I manually fixed it by setting TimedLoginEnable=False in /etc/gdm/custom.conf
* I think it should be somehow linked with the change of AutomaticLoginEnable option. E.g. disable TimedLogin if AutomaticLogin is disabled for that user.

/etc/gdm/custom.conf config excerpt before fix:

[daemon]
AutomaticLoginEnable=False
AutomaticLogin=d
TimedLoginEnable=true
TimedLogin=d
TimedLoginDelay=10
