REVISION SUMMARY
  In some rare cases, the ungrab keyboard request is processed later than
  the action of the key shortcut. This can make the application that try
  to grab the keyboard (e.g. in kwin) fail to do so. The solution is to
  use ungrab_keyboard_checked() and xcb_request_check() before emitting
  the shortcut signal.
