Could you report this upstream on KDE's Bugzilla?

Ah crap, I had completely forgotten about this. Thanks for following up and reporting the issue, Sam!
What about 22.12.3?
Still broken with both clang-15 and clang-16.
This has been fixed upstream https://invent.kde.org/network/kdeconnect-kde/-/merge_requests/540
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=2a0b7a7f7698823ddf3e67ebfc0d7d372fa73334 commit 2a0b7a7f7698823ddf3e67ebfc0d7d372fa73334 Author: Luna <luna.dragon@suse.com> AuthorDate: 2023-06-08 07:07:45 +0000 Commit: Andreas Sturmlechner <asturm@gentoo.org> CommitDate: 2023-06-08 11:35:19 +0000 kde-misc/kdeconnect: Fix builds using clang clang is more strict for syntax then gcc hence it was not possible to build kdeconnect with clang. This adds a patch from upstream that corrects this by explictly using the constructer as it should have in the first place.
