Git commit 9d55c52f76cf831584d71d60a8806688f37ea0cc by Kai Uwe Broulik. Committed on 21/09/2016 at 09:50. Pushed by broulik into branch 'Plasma/5.8'. [KeyboardDaemon] Don't call getCurrentLayout() in destructor It does X calls and might crash kded on logout. Since we already have a currentLayout member, there's no need to get it afresh.
