When akonadi uses the mysql backend, it starts a separate instance of mysqld (which ain't a bad idea, because it is) using configuration and data in the user's home directory. However, since /usr/sbin/mysld is setuid/setgid mysql, it cannot access the home directory, thus failing to read any configuration or data files. I don't know whether this is a gentoo-specific or a general akonadi problem, please defer me to upstream if necessary.

Additional symptoms for leading other users with this problem here: Akonadi error messages: * Akonadi server process not registered at D-Bus * Akonadi control process not registered at D-Bus * No resource agents found * Could not access the outbox folder
Definitely not the case anymore with current stable 5.1.51.
