Can confirm this happens on Neon on wayland as well.

*** Bug 370415 has been marked as a duplicate of this bug. ***
Comment 3 miku84 2016-10-11 06:44:00 UTC 
So the issue happens on wayland only.
Comment 4 Tony 2016-10-11 17:49:41 UTC 
(In reply to miku84 from comment #3)
> So the issue happens on wayland only.

Yes.
Comment 5 Carlos Olmedo Escobar 2016-11-21 20:44:43 UTC 
I'm hitting this bug in Neon too (neon-devedition-gitunstable-20161121-0806-amd64) only in the wayland session.

Comment 7 Patrick Silva 2017-01-29 16:28:44 UTC 
It`s still happening on plasma-wayland-devedition-gitunstable-20170128-2117-amd64.iso

Comment 11 Rainer Finke 2017-10-21 09:24:07 UTC 
I just want to confirm that this is still a bug in Plasma 5.11.1 on Wayland, KDE Frameworks 5.39 and Qt 5.10 beta on Arch Linux.

Comment 13 Fabian Vogt 2018-01-16 21:27:09 UTC 
From the code it looks like it can't work properly on non-X11 platforms.
I suppose as a workaround it would be possible to add

X-KDE-OnlyShowOnQtPlatforms=xcb;

to /usr/share/kservices5/fontinst.desktop.
Can someone confirm that this works? The icon should disappear in systemsettings.
Comment 14 bug2017 2018-01-17 12:22:07 UTC 
That workaround is working, it hides the font manager on wayland but not on X11

Is this going to be added to in the future? Hiding the settings until they become usable on wayland is much better than crashing systemsettings.
