Comment (by jrf):

 @peterwilsoncc When a plugin overloads a WP native method and then changes
 the return type from the documented expected return type to something
 completely different from and incompatible with the return type of the
 original method, do you really expect WP to handle that ?

 Cause that's what's happening here.
