Comment # 4 on bug 1108570 from Fabian Vogt

It seems to be a quirk in how NM sets up its DBus interface.

I reported that as https://bugs.kde.org/show_bug.cgi?id=400359 and wrote a
workaround patch.

Please try with libKF5NetworkManagerQt6 from
obs://home:Vogtinator:boo1108570/openSUSE_Factory and report back.
