Your traceback indicates, that the object itself does not object
to be copied. It's the destination that does not want the
object.

  The problem occurs in "_verifyObjectPaste".
  Its source comment says:

        # Verify whether the current user is allowed to paste the
        # passed object into self. This is determined by checking
        # to see if the user could create a new object of the same
        # meta_type of the object passed in and checking that the
        # user actually is allowed to access the passed in object
        # in its existing context.

Thus, it is probably a security issue:

  Either you are not allowed to call the ZClass constructor
  at the destination,

  or you are not allowed to access the object to be cloned
  at the destination.
