           Summary: Connection introspection with GetInterfaces does not
                    work
           Product: Telepathy
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: telepathy-python
        AssignedTo: telepathy-bugs at lists.freedesktop.org
        ReportedBy: alban.crequy at collabora.co.uk


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.
