great...many thanks for all this explanation! I've changed for the way you said [1] and it's working.
Just one more question: I don't know if this is related to telepathy but when I receive a message at Empathy and the chat window is not open, it appears a little box at the bottom of the screen with that message. I saw at the debug log that a new channel is being created. When I click this box, it opens the chat window but the messages received while the chat window was closed doesn't appears there. Do you know if there is some property of the request map that I should set to maintain these received messages with window chat closed?
