Before latest upgrade, starting Cantata made the media player icon show on kde system tray and media player shortcuts worked.
It is not the case anymore, however, If I start spotify client (which makes the media player appear), then cantata then stops
spotify, cantata then uses the media player shortcuts or the icon, it works.
