Comment 1 Massimo 2015-05-29 04:49:38 UTC

I've changed the windows decorations with

$ kcmshell5 kwindecoration

and reverted to org.kde.breeze's (default) decorations.

Now systemsettings5 does not crash anymore when accessing the windows decoration module.

The decoration previously was "Yosemite", downloaded via the "Get New Decorations" button.

I don't know if it's a bug of the theme, of the kwindecoration module or something else; even a poorly-written theme shouldn't trigger this behaviour IMHO.
