hildon-home "LED-Pattern" xdg desktop notification hint is not honored

[IMbackK]

https://github.com/maemo-leste/hildon-home/blob/0d32a53e8a18b69e9472d56ea26a19cba210a649/src/hd-incoming-events.c#L1387
suggests that hildon-home should activate the corresponding mce led pattern however this dosent happen, no dbus call to mce is ever issued.

how to reproduce:
notify-send -h string:LED-Pattern:PatternCommunicationSMS test
or look as sphones dbus output

expected result: hildon-home activates the corresponding mce pattern
actual result: nothing happens

modest seems to call MCE to get the LED patterns:

void
modest_platform_push_email_notification(void)
{
    gboolean screen_on, app_in_foreground;

    /* Get the window status */
    app_in_foreground = hildon_program_get_is_topmost (hildon_program_get_instance ());

    screen_on = modest_window_mgr_screen_is_on (modest_runtime_get_window_mgr ());

    /* If the screen is on and the app is in the
       foreground we don't show anything */
    if (!(screen_on && app_in_foreground)) {

        modest_platform_play_email_tone ();

        /* Activate LED. This must be deactivated by
           modest_platform_remove_new_mail_notifications */
#ifdef MODEST_HAVE_MCE
        osso_rpc_run_system (modest_maemo_utils_get_osso_context (),
                     MCE_SERVICE,
                     MCE_REQUEST_PATH,
                     MCE_REQUEST_IF,
                     MCE_ACTIVATE_LED_PATTERN,
                     NULL,
                     DBUS_TYPE_STRING, MODEST_NEW_MAIL_LIGHTING_PATTERN,
                     DBUS_TYPE_INVALID);
#endif
    }
}

Which is also a unnescary duplication, as for modest group notifications hildon home has allready set the email pattern to on due to this behavior being "hardcoded" in hh
