The crash seems to be caused by this change in kcmutils 5.67.0:
https://cgit.kde.org/kcmutils.git/commit/?id=f52314e6cf194c64edd331a98a31803bbd971484
Reverting this fixes the crash for me.

But I just noticed that the original crash reported here is something
completely different, so let's keep them separate (I'll reopen bug#417396).

About the original crash reported here, I cannot reproduce that at all, on the
same distribution (openSUSE Leap 15.1 + additional KDE repos).
Maybe it's fixed already?
