Reproduces the bug 

Description of Problem:

Accessing almost all properties on the ALAssetsGroup and  ALAsset objects
returned by ALAssetsLibrary.Enumerate and ALAssetsGroup.Enumerate causes a
ArgumentNullException.


Steps to reproduce the problem:
1. See attached project.


Actual Results:
ArgumentNullException

Expected Results:
The actually property data.

How often does this happen? 
All the time.

Additional Information:

I have only tried to do this on a actual device, so it may work on the
simulator.  My simulator has no photo's so I can't try it.

See MainView.cs for the main bug implementation.
