-----------------------------+----------------------------------------------
 An argument isn’t being marshalled properly to mutable array KVC
 accessors.

 {{{
 class KVCTest
   def initialize; @a = []; end
   def countOfThings; @a.size; end
   def objectInThingsAtIndex(i); @a[i]; end
 end
 KVCTest.new.valueForKey 'things'

 irb(main):015:0> KVCTest.new.valueForKey 'things'
 TypeError: no implicit conversion from nil to integer
         from (irb):11:in `[]'
         from (irb):11:in `objectInThingsAtIndex'
         from bin/irb:12:in `<main>'
 }}}

 Not sure why objectInThingsAtIndex: is getting a nil arg here.
