Debugging output of various sorts

After updating to Build 20191016 I started having issues with Brave, Chromium,
Firefox, and anything Electron-based as well. Anything Chromium-based started
segfaulting on X11, yet they were fine on Wayland, and they did not produce any
crash report or error report or anything of the sort. Attached here are some of
the relevant debugging output figured out courtesy of the help of /u/Vogtinator
over at /r/OpenSUSE and the problem seems to be related to the GTK appmenu
(Global Menu I believe). 

Here are some other hwinfo if they are relevant: 
Operating System: openSUSE Tumbleweed 20191018
KDE Plasma Version: 5.17.0
KDE Frameworks Version: 5.63.0
Qt Version: 5.13.1
Kernel Version: 5.3.6-1-default
OS Type: 64-bit
Processors: 8 �� Intel�� Core��� i5-8250U CPU @ 1.60GHz
Memory: 7,6 GiB of RAM

I have yet to check out whether removing the relevant culprits solves this
issue, and I will update it here if it does.
