Since recently KDE's diskmonitor is reporting error message 

Fehler beim Laden der QML-Datei:
file:///usr/share/plasma/plasmoids/org.papylhomme.diskmonitor/contents/ui/main.qml:22:1:
module "QtQuick.Layouts" version 1.11 is not installed

If I check the mentioned file
file:///usr/share/plasma/plasmoids/org.papylhomme.diskmonitor/contents/ui/main.qml:22:1
I find the important lines 

  import QtQuick 2.3
  import QtQuick.Layouts 1.11

The second one I have to change into 

  import QtQuick.Layouts 1.3

to get rid of the error message in KDE's tray area showing diskmonitor.
Seems QtQuick.Layouts did change the version...

Regards
Ralf
