When displaying some animated images, they look somewhat broken.  Here's
a test case:

(url-retrieve
 "http://icanhascheezburger.files.wordpress.com/2010/12/funny-pictures-gifs-standing-cat.gif?w=215&h=205"
 (lambda (status)
   (goto-char (point-min))
   (search-forward "\n\n")
   (let ((data (buffer-substring (point) (point-max))))
     (pop-to-buffer "*animate*")
     (insert-image
      (create-animated-image data 'gif t)))))

Apparently these are GIF images that have a background images, and the
rest of the frames are of the "combine" type.  Emacs doesn't seem to do
the right thing in that case, although other animated GIFs look fine.

This was fixed a while ago, so I'm closing the bug.
