Jelly is dynamically typed, so any value might show up in any position.  In this case, a value shows up in the slot in the serialization of a method object which indicates that method's class might be any object, but it has to be a class.

It's not clear that there needs to be a better error message here; you'll only get this message if you have corrupt data on the wire, since a correct implementation of PB will never put anything other than a class in that slot.

(Except I think it might be broken in the face of new-style classes; ClassType is the old-style class type, 'type' is the new one, so, that should probably be fixed, as per your other thread...)
