I've debugged it down to an error in eshell-shuffle-files. With XEmacs 
21.4.20 and eshell from the XEmacs package repository, we have

       ((and attr-target
	     (or (not (eshell-under-windows-p))
		 (eq system-type 'ms-dos))
	     (setq attr (eshell-file-attributes (car files)))
	     (nth 10 attr-target) (nth 10 attr)
	     (= (nth 10 attr-target) (nth 10 attr))
	     (nth 11 attr-target) (nth 11 attr)
	     (= (nth 11 attr-target) (nth 11 attr)))

With GNU Emacs 23 and the builtin eshell from the CVS repository, where
it works, we have

       ((and attr-target
	     (or (not (eshell-under-windows-p))
		 (eq system-type 'ms-dos))
	     (setq attr (eshell-file-attributes (car files)))
	     (nth 10 attr-target) (nth 10 attr)
	     ;; Use equal, not -, since the inode and the device could
	     ;; cons cells.
	     (equal (nth 10 attr-target) (nth 10 attr))
	     (nth 11 attr-target) (nth 11 attr)
	     (equal (nth 11 attr-target) (nth 11 attr)))

So the error is already known (see the comment); XEmacs shall sync eshell.
