exec dbus-launch gnome-session

Very recently, I started getting similar complaints from
gnome-settings-daemon.
I don't think you should have to use dbus-launch.

I was able to recover gnome-settings-daemon after logging in (with just
gnome-session):

/usr/pkg/libexec > dbus-launch ./gnome-settings-daemon

and it started and my foot and logout icons came back and fonts got more
normal....
