gdbusconnection.c:4231 is the last of the lines I've quoted here:

  if (!data->vtable->set_property (data->connection,
                                   g_dbus_message_get_sender (data->message),
                                   g_dbus_message_get_path (data->message),
                                   data->interface_info->name,
                                   data->property_name,
                                   value,
                                   &error,
                                   data->user_data))
    {
      gchar *dbus_error_name;
      g_assert (error != NULL);

So the bug here is that something, somewhere in the
gnome-settings-daemon process, has a set_property() callback
that fails without correctly setting the error.

Searching the gnome-settings-daemon source code, the only obvious
possibility is in the power plugin. Aron, please try this and see
whether it works better for you:
