SUMMARY
kded5: Segmentation fault when I plug in Dualshock 4 (CUH-ZCT2E) controller
using xf86-input-libinput. The problem does not occur with xf86-input-synaptics
installed which seems to replace the libinput one as it changes the KDE system
settings touchpad options.
STEPS TO REPRODUCE
1. Plug in Dualshock 4 controller.
OBSERVED RESULT
System tray icons disappear and then reappear shortly after. Some of them are
missing (Discord). Getting notification about network connection again just
like after system boot.
