I had these decorations installed in ~/.local/share/aurorae/themes air-oxygen ambiance cupertino Diamond ElementaryLunaAurorae Ember light nano-deco NewAir osx perfection PlasmaNext-windowdecoration-ideas seven Tenuto-Light Tenuto-Light-ActiveStrong I moved all of them out of that directory, then moved them back one by one. For each of these decorations, I went into Window Decorations, scrolled through the previews and quit systemsettings. All but one decoration caused this crash, PlasmaNext-windowdecoration-ideas, and that one had no preview. So it seems that it is the preview of these decorations that causes the crash.
I tried to reproduce it and these were my results: Themes installed: org.kde.breeze Freeze Kdust Plastik It only crashes when I click OK. Not when I change the theme with apply. Going from: Plastik -> Kdust CRASH Kdust -> Plastik no crash Plastik -> Kdust CRASH Kdust -> Freeze CRASH Freeze -> org.kde.breeze no crash org.kde.breeze -> Plastik CRASH Hope this helps. I have never reported bugs before ;)

My decorations: air-oxygen, widget style: Oxygen, desktop theme: Air. The original crash I reported in bug #347374 happened when I switched decorations from org.kde.oxygen to air-oxygen. But as I was typing this comment I went to the System Settings to see theme names and it still crashed when I pressed the Overview button to exit the decorations selection screen, although I made no changes at all.
I'll add that I only have air-oxygen in ~/.local/share/aurorae/themes.

I can reproduce a bit differently on Debian testing, with Qt packages 5.7.1~20161021-5, systemsettings 5.8.2 (and 5.8.4 from unstable, but I don't think it matters) and Frameworks 5.27. It happens when I click on "Desktop Behavior" and then "Screen locking", without touching any widget. It crashes when I click to "All Settings" or (as other reported) when I close it. Maybe the screen locking uses some special setting?
Oh, and I use the Oxygen style for widgets, but it happens with Breeze too. Breeze for window decoration.
