I updated kaos yesterday (just update, did not test any application at all)

Today Kmail is not working, it says that mysql has an error, here is the akonadi server error log. what can I do to solve this issue?

I changed to SQLLite (as the proposed solution from april's issue) and seems to work, should I continue using SQLLite?

Akonadi Server Self-Test Report
