Well, I just added

if (seat && !streq(seat, "seat0")) {
	pam_syslog(handle, LOG_WARNING,
		"Ignoring vtnr %d for %s which is not seat0", vtnr, seat);
	vtrn = 0;
}

because in my case vtnr was coming from pam_getenv(XDG_VTNR), and
get_seat_from_display() isn't called.

But thank you, my system is a bit more usable now =)
