Fun with Akonadi Dataengine

[David Baron]

Got to try it.

connectSource to ContactCollections.
dataUpdated() is called and I connectSource to ContactConnection-# that it 
gives me in the data.uniqueKeys()

dataUpdated() is never called again.

The console shows all the contacts being added int but the program never sees 
them.

1. What do I do now?
2. How do I know when all the data has been loaded--no more calls to 
dataUpdated() are going to happen?
