bug#4107: 23.1.50; Invalid image size (see `max-image-size') [146 times]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

The bug report is based on GNU Emacs 23.1.50.1 (i386-apple-darwin9.8.0,
 NS apple-appkit-949.54) of 2009-08-10 on neutron.local

  1.  Emacs -q
  2.  (load "org")
  3.  M-x customize-variable RET org-modules RET
  4.  C-x 4 b to switch and show the *message* buffer

You will see: Invalid image size (see `max-image-size') [59 times]

And now typing C-x o will increase that number each time.
