Comment # 4 on bug 1139463 from Ms Hmm

Uninstalling qqc2-desktop-style gives me the following error when launching
plasma-discover in Konsole:
invalid kns backend! "/usr/share/knsrcfiles/ksysguard.knsrc" because: "Config
group not found! Check your KNS3 installation."
adding empty sources model QStandardItemModel(0x561cd80b9500)
Segmentation fault (core dumped)

Uninstalling Discover (and backend pacakages) and then replacing them with the
5.16.2 packages from the KDE:Frameworks5 repo gives this error on launch:
file:///usr/lib64/qt5/qml/QtQuick/Controls.2/org.kde.desktop/private/MobileTextActionsToolBar.qml:62:

I've searched on Google for anyone else having similar problems, but the only
ones I can find are from more than a year ago when Plasma 5.12 came out.
Searching KDE forums and KDE bugs draws a blank, so at the moment I think it is
openSUSe specific.
