Akonadi/MySQL problem this morning

[Timothy Murphy]

I'm unable to start KMail in Fedora-18, with the error message
"The Akonadi personal information service is not operational"

Further details are:
"MySQL server log contains errors.
Akonadi control process not registered at D-Bus.
Akonadi server process not registered at D-Bus."

I think this happened on updating kdepim last night
as part of a general update after installing Fedora-18.
(KMail worked find under Fedora-18 before the update.)

The error seems to lie in mysql-server, so I have downgraded this,
which required downgrading mysql and mysql-libs also:
--------------------------------
[tim at blanche ~]$ sudo yum downgrade mysql-server mysql-libs mysql
--------------------------------
But this didn't do the trick ...

MySQL error log reads:
