UI freeze exception akonadi start/stop progress dialog

Whenever akonadi starts or stops a progress dialog is shown. The only use of this dialog is to indicate that something is happening (so not really progress anyway).
Apparently this dialog is however scary and confusing to the average user and was already removed from KDE trunk, hence it should also be removed in our packages of KDE 4.4... for which a UI freeze exception would be very good to get :)
