Which Emacs version do you use? I have: 
"GNU Emacs 21.3.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars) of 
2004-08-03 on raven, modified by Debian",
but the bug was also reported on some earlier SuSE version.
Here is a test example:

(progn
  (find-file "foo.el") 
  (insert "a\nb\n\c\n") 
  (put-text-property (point-min) (point-max) 'invisible t)
  (comment-region (point-min) (point-max)))

the result is:
a
b
c;; 

if the fourth line is commented, it is:

;; a
;; b
;; c
