Description Alban Crequy 2009-09-08 03:18:27 UTC 
In my Rhythmbox plugin, I use this code:

http://git.collabora.co.uk/?p=user/alban/rhythmbox-plugin-telepathy.git;a=blob;f=rb-tp-export/__init__.py;h=15d93127d5e5ca64bf8597b3c2b646f6e55cff98;hb=HEAD#l138

  conn = Connection(service_name, path, self.bus)

  # FIXME: I don't understand why _valid_interfaces is not correctly
  # updated after GetInterfaces is called in the constructor
  conn._valid_interfaces.add(CONNECTION_INTERFACE_REQUESTS)

  channel = conn.create_channel(...

Modifying "_valid_interfaces" manually should not be needed. I check with dbus-monitor, and GetInterfaces is called successfully and returns the right interfaces (including the "requests" interface). But then _valid_interfaces does not contain it, so create_channel does not work.

As a workaround, I add the requests interface manually, but there is a bug somewhere.

Are you waiting that the Connection object is ready?
You can do that by passing a ready_handler to the constructor or call conn.call_when_ready().

He's not.
