No title elements with XeTeX?

[Axel Dessecker]

When trying to view a scrartcl document with a title or some other title 
element by using xelatex, I have a LyX crash. I can see the following details:

This is LyX 2.3.3, Qt 5.9.4, Linux (openSUSE Leap 15.0).

MWE enclosed. Can anyone reproduce this?
