KMail doen't startup fully.

Installed system : Knoppix 7.4.0

Dear Forum Member,

KMail doesn't startup fully.

Error message:
The Akonadi personal management service is not operational.

Details; First Error message:

The Akonadi control process is not registered at D-Bus which typically means it was not started or encountered a fatal error during startup.

What's wrong? How can I solve this problem?

Thank you.
