-- Information about the crash:
I can consistently make System Settings crash if I switch too fast between
KCMs. It's easier to reproduce in the Appearance section. Since I'm using a VM,
switching between KCMs is slower than normal, so it will probably be harder to
make it crash on a real machine. On the VM I can make SySe crash with the mouse
cursor very easily, for a real machine I suggest the following:
1. Go to the Appearance category
2. In order to switch between categories very fast, spam the up/down arrow and
enter keys in rapid succession. This will hopefully make it possible to
reproduce the issue.
This issue is NOT present on Plasma 5.27
Unfortunately I couldn't install the debug symbols because the proccess
responsible for doing that in Dr. Konqi crashes.
The crash can be reproduced every time.
