Can confirm this. Kontact crashes every time we I go to Settings -> Configure Kontact. This was not happening before updating to Plasma 5.18. 

Operating System: Arch Linux 
KDE Plasma Version: 5.18.0
KDE Frameworks Version: 5.67.0
Qt Version: 5.14.1
Kernel Version: 5.4.19-1-lts

That's likely unrelated, as this bug report is nearly 2 years old...

You probably experience bug#415634, which I suppose is caused by a change in KDE Frameworks 5.67.0 (kxmlgui).

The originally reported crash here cannot possibly happen anymore, it was crashing in Qt5Script but the latest grantlee version doesn't even use that at all anymore a it has been ported to Qt5QML.

Erm, I mean kcmutils. At least that's where the crash from bug#415634 is located.

New crash information added by DrKonqi

kontact (5.11.3) using Qt 5.13.2

- What I was doing when the application crashed:

Open Kontact, go to settings > configure kontact.

That is bug#417396, a regression in KDE Frameworks 5.67.0 that's already fixed (to be in 5.68.0).
Totally unrelated to this bug report though, which is 2 years old.
