What does ApperKCM::search() do that it could cause a crash inside the system settings list views?
It's not system settings it's own categories view, this is a crazy random bug that I never see here, but some people have it tho I have no clue what happens on their system to crash like this..
bug 285316 and bug 284516 are possibly duplicates.

From bug 289717: "Applications inside software management needs only one click and I was double clicking it, when I do this it crashes, but if I click once , wait , and click again, then it doesnt crash. I think there is already another report about this one."
From bug 290591: "I open Apper and when a do double click on development subcategory, it chased."

Looks like something starts a local event loop, so that double clicking causes reentrancy bug.
