 Attached is the log of AcousticMeasure taken on 258 when launching the
 activity when there is no connection.

 Activities as been working around this issue like this.

 {{{
 # Get the Presence Service
         self.pservice = presenceservice.get_instance()
         try:
             name, path = self.pservice.get_preferred_connection()
             self.tp_conn_name = name
             self.tp_conn_path = path
             self.conn = telepathy.client.Connection(name, path)
         except TypeError:
             _logger.debug('Offline')
 }}}

 Anything else we could do here to not duplicate code? Or has this been
 handled already by the latest sharing code?
