This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:

I got this backtrace when trying to display the keyboard layout on a gnome+wayland session. This always immediately results in a SEGV. When specifying GDK_BACKEND=x11, it crashes at a later point in execution or runs fine.

Comment 16 Matthias Clasen 2016-08-31 22:43:05 UTC
In theory, it should be possible to make gkbd-keyboard-display work under wayland, since we're using xkb there too. If that is too hard, we should at least disable the button in the region panel under wayland.

And also in the gnome-shell keyboard-switcher dropdown menu, which is only visible in case you have multiple keyboard layouts configured.

Having it ported would be preferred, of course.

Comment 19 Christian Stadelmann 2016-11-05 16:39:08 UTC
the keyboard layout window is now using X11 (enforced). The crasher is gone for me now.

Comment 20 Christian Stadelmann 2017-01-18 14:17:15 UTC
Can somebody please close this bug, it is fixed upstream on Fedora 25 for quite some time.
