I guess you should be able to got this message using
channel[CHANNEL_TYPE_TEXT].ListPendingMessages()
See
http://telepathy.freedesktop.org/spec.html#org.freedesktop.Telepathy.Channel.Type.Text
We should probably call it in set_received_callback()

Btw, it seems we never acked received messages. Is that intentional?
According the spec each message should be acked when they are displayed.

You can find the type of the channel by calling 
GetChannelType() on the channel object.

Or maybe we could just add the channel type in the signal.

I agree, displaying an incoming chat as an invitation is much more saner
than automatically launch Chat.
