OK, a little further. I think the problem may be with

   function Get (Val : JSON_Value) return JSON_Array is
   begin
      return Val.Data.Arr_Value.Arr;           <<<< exception here
   end Get;

which is expecting Val to be of type JSON_Array_Type, i.e. an array, but
it isn't; it appears to be some sort of nested array-like structure, and
I can recognise the names from the pair_settings. You need someone who
understands GNATCOLL.JSON (there don't seem to be any examples in the
source).
