[Telepathy] What am I doing wrong?

[Jonas]

I'm experimenting with D-Bus and Telepathy as I like the concept.. But
I find the documentation a lil confusing.. I have written a piece of
code that refuses to work as it should, can someone help?

When I run it I get this message:

Error: Method "GetMandatoryParameters" with signature "s" on interface
"org.freedesktop.Telepathy.ConnectionManager.gabble" doesn't exist

Here's the code (please reply to my email as I'm not registered on the
mailing list).

    {

                  error->message);

      return 1;
    }

                    dbus_g_error_get_name (error),

      else
        g_printerr ("Error: %s\n", error->message);
      g_error_free (error);
      return 1;
    }

  /* Now we should have the results in 'parameters' */

  g_object_unref (proxy);

  return 0;
}
