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).
