    GDBus: If exiting b/c remote peer disconnected and error is set, print it
    
    This should make things easier to debug:
    
      g_dbus_connection_real_closed: Remote peer vanished with error:
      Underlying GIOStream returned 0 bytes on an async read
      (g-io-error-quark, 0). Exiting.
