The app receives an empty address book (as opposed to NO address book), an empty calendar (as opposed to NO calendar), and in your location case, the app gets the "rough" location provided by the cell network.

Throw nulls (or better yet, exceptions) where an application expects parseable data (and given the current permission paradigm, has every right to expect usable data) and you can very reasonably expect breakage.

This is why the feature needs to cook for longer, not some malice aforethought on Google's part as GP claims.
