The keypath:

ANY personalNames.value.gedcomString CONTAINS "..."

is composed of the following keys:

GCIndividualEntity has a KVC-compliant collection property called 
_personalNames_ which is an array of GCPersonalNameAttributes which each have a 
GCValue property called _value_ which again have an NSString property 
_gedcomString_ (by the way these are NSObjects, not Core Data).

I am not binding to the keypath in my xib, but obtain the predicate via code. 
The array controller is bound to a property "individuals" on File's Owner (my 
NSDocument subclass).

When I've loaded the file, I set self.individuals = self.context.individuals, 
causing a table view bound to the array controller to show the objects; this 
works as expected, as well as a detail-view connected to the controller's 
selection. I then attempt to set the array controller's predicate and 
immediately it dies with the mentioned exception.
