Crash when scrolling through xdg-desktop-portal-kde Application Chooser

[ratijas]

I was inspecting xdg-desktop-portal-kde dialog — the one for choosing an application to open a file with. GammaRay crashed while I was scrolling the huge lists of all installed apps back and forth.

It happened at least three times now with a similar stacktrace, so it's kinda consistent.

Stacktrace
