When I start stream-engine in a console, I can successfuly call with Empathy. But when I let the D-Bus activation starting stream-engine, the call never succeeds and I don't see the preview video. Empathy complains that a stream-engine method does not exist on the bus: TpCall: Error calling handle channel: Method "HandleChannel" with signature "sosouu" on interface "org.freedesktop.Telepathy.ChannelHandler" doesn't exist However stream-engine doesn't crash and I see the method exists on the bus. This is a race when stream-engine starts. In current stream-engine code, the well-known name is requested before the object is created. See function tp_stream_engine_register() in stream-engine/src/tp-stream-engine.c: 1. tp_cli_dbus_daemon_run_request_name() 2. dbus_g_connection_register_g_object() 3. register_dbus_signal_marshallers() This order is wrong.
Patch on http://monkey.collabora.co.uk/stream-engine-alban-fixes/ But I still don't manage to get stream-engine working with D-Bus activation.
