[Telepathy] problem with current empathy git

[Nicolò Chieffo]

Hello, when I run empathy, I see lots of messages like this:
** (install/bin/empathy:12298): DEBUG:
mission_control_get_presence_actual: MC not running.
** (install/bin/empathy:12298): DEBUG:
mission_control_get_presence_message_actual: MC not running.
** (install/bin/empathy:12298): DEBUG:
mission_control_get_tpconnection: MC not running.
** (install/bin/empathy:12298): DEBUG:
mission_control_get_connection_status: MC not running.

what's wrong with my installation?
I have compiled empathy (git master) by myself, and I have those
ubuntu packages:
