main.qml (minimal example)

inside a qml KCM put a Kirigami.ItemViewHeader and it gets grumpy:

I'm attaching a sample file, easiest to drop it in an existing KCM to see the problem.

I suppose the problem is that it assumes the presence of applicationWindow()
Comment 3 Harald Sitter 2020-08-31 10:46:07 UTC 
Yep. Probably needs some if-elseing.
