Comment 1 Christoph Feck 2017-11-24 00:09:35 UTC

Unsure why KWayland is run in non-GUI thread, or why it references QPixmap, which can only be used from main thread.

Comment 2 Tony 2018-03-30 05:53:28 UTC

Can't reproduced anymore with recent updates. Marking as "Works for me" since i have no idea if it is properly fixed.

Comment 3 Tony 2018-03-30 06:08:47 UTC

Created attachment 111731 [details]
New trace

To reproduce always:
Open system settings, click on "Printers".
Fill the root password prompt and then close the window.
