Description of problem:
Per https://bugzilla.redhat.com/show_bug.cgi?id=2374526#c1, "When I reinitialised from suspension via KScreenLocker, Plasma Shell was hung. It momentarily stopped being so, during which I attempted to invoke GNOME Abrt. I attempted to log out whilst it wwas hung again, but GA finally launched. After some time, it killed it, evidently as a last resort when log out has failed."
