Title:
  LightDM gets "Error updating CanGraphical" warning when a logind seat
  is removed

Status in Light Display Manager:
  Triaged
Status in Light Display Manager 1.10 series:
  Triaged

Bug description:
  I'm testing LightDM 1.10.2 automatic multiseat support (backported
  from 1.12 series) with logind-check-graphical enabled, and I've
  observed that, if a seat is removed from logind, I get the following
  message in lightdm.log:

  WARNING: Error updating CanGraphical:
  GDBus.Error:org.freedesktop.DBus.Error.UnknownObject: Unknown seat

  Maybe login1.c code should be updated so that seat_property_changed
  callback should not try to update CanGraphical status if a seat is
  removed (including stopping/stopped flags in Login1SeatPrivate struct
  could help).
