Comment 1 Christoph Feck 2018-10-11 16:52:52 UTC

You are using Qt packages installed in /opt, which means you are not using official distribution packages.

If this is reproducible with official packages, please add a new backtrace with debug symbols.

Comment 2 Kwanza.Pili 2018-10-14 17:22:19 UTC

I think the problem I had was due to upgrading to QT-5.11.2 without rebuilding the KDE apps. I have now installed systemsettings5-5.14.0 and the issue seems to be resolved. 

I don't think that the location of the installation is relevant here. All I do is source the RPMs from opensuse, compile them, and then install them in /opt/, /usr/local or wherever. This has worked well before and works again.
