A possibly relevant merge request was started @ https://invent.kde.org/pim/akonadi-calendar/-/merge_requests/30
Comment 2 David Faure 2022-06-30 14:55:28 UTC 
Git commit 26694e8c82562eac2fdbdb6fa85f56b27fca82a0 by David Faure.
Committed on 30/06/2022 at 14:32.
Pushed by dfaure into branch 'release/22.04'.

Fix crash when clicking on dismiss, sometimes.

client->dismiss(this) ends up setting client to nullptr, so
the disconnect() warns about null receiver and doesn't actually
disconnect.

(This is similar to 24f3853f14ec in master)
