I solved the problem. It'a an AppArmor issue.

You need to edit your AppArmor configuration.

vim /etc/apparmor.d/usr.sbin.mysqld-akonadi

The content looks like this from the beginning. I only added a lot's of stuff
at the top.

```
# vim:syntax=apparmor

#include <tunables/global>

/usr/sbin/mysqld-akonadi {
  #include <abstractions/base>
  /usr/sbin/mysqld-akonadi r,
  /usr/sbin/mysqld cx,

  profile /usr/sbin/mysqld {
    /run/user/1000/akonadi/default/mysql.pid rwmk,
    /run/user/1000/akonadi/default/mysql.socket rwmk,
    /run/user/1000/akonadi/default/mysql.socket.lock rwmk,
    /sys/devices/system/node/* r,
    /sys/devices/system/node/ r,
    /etc/mysql/* r,
    /etc/mysql/mysql.conf.d/ r,
    /etc/mysql/mysql.conf.d/* r,
    /sys/devices/system/node/node0/meminfo r,
[more lines]
```

Afterwards reload the apparmor configuration for the file.

apparmor_parser -r /etc/apparmor.d/usr.sbin.mysqld-akonadi

You can restart Akonadi via the Akonadi console or a system restart now.

At least it worked for me and I'm fine again. :-)
