Bluetooth audio via pulse doesn't function unless I chant the magic incantations

[Russ Dill <russ.dill@gmail.com>]

I have ubuntu lucid (its just karmic+2.6.32-rc5) and I can only get
pulseaudio to detect my Sony DR-BT50 headset if I send some dbus
commands:

addr=00:1a:80:67:63:2c
hci=$(dbus-send --print-reply --system --dest=org.bluez /
org.bluez.Manager.DefaultAdapter | tail -n 1 | cut -f 2 -d '"')
dev=$(dbus-send --print-reply --system --dest=org.bluez $hci
org.bluez.Adapter.FindDevice string:$addr | tail -n 1 | cut -f 2 -d
'"')
dbus-send --print-reply --system --dest=org.bluez $dev org.bluez.Audio.Connect

Additionally, the device shows up under the gnome bluetooth-properties
applet under "Known devices" with the gold star and the keys. The
connected plug doesn't appear until I exec the above commands.
Clicking the plug without the above commands does nothing.

bluez 4.51-0ubuntu2
libbluetooth3 4.51-0ubuntu2
pulseaudio 1:0.9.19-0ubuntu4
pulseaudio-module-bluetooth 1:0.9.19-0ubuntu4

(after above commands)

How can I get my machine to automatically pair with this headset?
