Profile registration with bluez using dbus/gio.

[JT Harkey <jtharkeyjr@xxxxxxxxx>]

I'm trying to understand the process of registering a profile with
bluez using the dbus/gio method. When I call RegisterProfile
everything is good. I check my GError and it's NULL and my return
value is an empty GVariant. However, I can't see the new profile in
D-Bus using d-feet and I cannot connect to it using a my test device.
Sdptool also can't find it.

I've searched the web for a couple of weeks now and have asked on
StackOverflow. Below is a link to that, which has a more full version
of my code. I've only posted what I believe are the most important
bits here.

I seem to be missing a step or don't fully understand the process. Can
someone please help me understand what I'm missing? I've run out of
ideas since I don't get any error information back.
