[Pharo-project] DirectoryEntry>>copy - boom

Hello all, Sorry to keep grumbling about (aguably) faulty use of inheritance, but I've hit another one. Try FileDirectory default entries first copy. It complains about variable size instances. I have no idea what to make of this. Anyone? Regardless of the nature of the real defect, I would argue that DirectoryEntry should not be derived from a collection; at most it should hold a collection in an instance variable and provide accessors.
