It also happens with me. In my multiseat system, if I logout on a son-seat0 seat (which has allow-user-switching=false by default), lightdm fails to start a greeter on that seat:
DEBUG: Seat: Display server stopped
DEBUG: Seat: Active display server stopped, starting greeter
DEBUG: Seat: Stopping; failed to start a greeter
DEBUG: Seat: Stopping
DEBUG: Seat: Stopped
I guess the problem is related to seat_switch_to_greeter() calls in session_stopped or display_server_stopped callbacks in seat.c
