NullReferenceException inside GetPropertyByName

The bug is here type.GetProperty(parts[0]).PropertyType. GetProperty returns null, so this will explode and is never caught. Obviously this was hard to catch because it only happens when you are accessing a nested property.

Thank you! The fix is included in 1.7.2.
