kdeconnect is broken in 20.09

[edolstra]

Describe the bug

The kdeconnect widget in the KDE panel shows:

Error loading QML file: file:///nix/store/78r8ihcgk25cj91d5bk8l5z6xcvxqli9-kdeconnect-1.3.5/share/plasma/plasmoids/org.kde.kdeconnect/contents/ui/main.qml:25:1: module "org.kde.kdeconnect" is not installed

Also, going to the "KDE Connect" panel in the KDE System Settings shows the error message The shared library was not found.

It's possible we should update it: https://invent.kde.org/network/kdeconnect-kde/-/tags thought it's not clear whether we should choose 20.08.1 or 1.4.0. I pushed some new dependencies we'll need in order to update it in #99956 . Here's a diff for the kdeconnect update, which doesn't work, hence I didn't push it to #99956 :

Applying this patch causes ld errors. Using the same patch but libsForQt514.callPackage for kdeconnect is closest I got, but it fails with an unfound kcmutils_version.h include.

we indeed should use 20.08.1.

[doronbehar]

Fixed in https://invent.kde.org/network/kdeconnect-kde/-/merge_requests/328

[doronbehar]

Updating kdeconnect is inseparable from #99956 so I'm pushing it there.

[edolstra]

This issue still exists on master and release-20.09.

I noticed a similar problem with the printer widget in the KDE panel:

[edolstra]

Yeah, mixing 3 different versions of Qt in one system really isn't ideal...

[doronbehar]

A similar issue we had fixed in #99956 appears with the set kdeApplications. See #100707 .
