I had a quick look at the Tumbleweed package, and the problem apparently is that /usr/share/plasma/plasmoids/org.kde.plasma.networkmanagement/metadata.desktop is a symlink to ../../../kservices5/plasma-applet-org.kde.plasma.networkmanagement.desktop . (but I actually don't really see anything wrong with that) Shouldn't cause a problem though as there's a metadata.json as well.
