After logging in, kontact automatically starts in my session. However, when hovering over the system tray item, it shows the 'busy cursor'.

Starting kontact manually from the command line yields:

where the last line is repeated.

Kontact is unresponsive and not usable, no matter how long I wait.

Manually starting the akonadi server with 'akonadictl start' on the command line causes kontact startup to continue.

On a maybe related note: KMail starts up without problems, starting the akonadi server if it is not running.
