The odd thing here is that this does not happen on the first connection.
Akonadi on startup connects once to the database to make sure it's there, it's the right version, and all the tables it needs are present. Then it disconnects again. It later reconnects with actual "worker" connections. The initial connection works, it's the later "worker" connections that fail with above error.
Checking debugging output from akonadi one can clearly see that:
bash-4.4$ akonadictl start

done.

Also notable is that if one prevents akonadi from closing the initial connection (by commenting the appropriate line in the code), future "worker" connection attempts succeed.
This behavior is the same with the Qt4 and Qt5 versions of akonadi. Considering this I'm rather tempted to see a bug in the connector rather than akonadi or Qt, especially since none of this happens with libmysqlclient.
