It's much better than it used to be, but I'm still seeing some glitches.

With emacs -Q and the latest bzr, eval the following:

(url-retrieve
 "http://icanhascheezburger.files.wordpress.com/2011/08/0848b876-a808-4614-ac26-9285d46cc5f7.gif"
 (lambda (status)
   (goto-char (point-min))
   (search-forward "\n\n")
   (let ((data (buffer-substring (point) (point-max))))
     (pop-to-buffer "*animate*")
     (let ((image (create-image data 'gif t)))
       (insert-image image)
       (image-animate image nil 60)))))

One single frame in the animation looks broken.  That seems to be the
case with all my test cases where the image displays buggily.  (But most
animated gifs display properly now.)  Could it be a off-by-one error of
some kind?
