Since your modifying the text within the region, the region end moves.
You should perhaps use markers to track these moves:
(defun insert-empty-lines (beg end)
(interactive "r")
(let* ((end-marker (make-marker))
(end-marker (set-marker endm end)))
(save-excursion
(goto-char beg)
(while (re-search-forward "\n" end-marker t)
(replace-match "\n\n" nil nil)))))
See (info "(elisp)Markers")
