Subject: 23.0.60; displaying SVG leaks memory
Date: Sat, 19 Jul 2008 11:34:12 +0200 (CEST)

The following form makes Emacs use increasingly more memory:

   (progn
     (find-file "~/emacs/etc/images/splash.svg")
     (while t
       (image-toggle-display)
       (redisplay)))

Memory use remains bounded if I instead use e.g. ".../splash8.xpm".

Does the following patch fix the memory leak for you?
