[Telepathy] How do I receive channels in an observer client?

[Mystilleef]

I think I'm missing a step to help my observer receive
incoming media channels.

Here's what I've done.

1) I've registered an Account with the AccountManager

2) Via the Account I've requested the presence to be Available.
If I'm not mistaken this automatically sets up a connection.

3) I've initialized a simple observer client and registered
it with the AccountManager and it has a name on the bus.

Code for the observer client: http://pastebin.com/zvEc8HeK

Yet, I can't receive any media channels.

P.S. The only time I can receive media channels is when I
have Empathy running.

What step am I missing? Do I need to initialize and prepare
a ChannelDispatcher?

I have _neither_ an approver or handler client implemented
yet. Does this matter?

Thanks
