[wp-testers] Linked images produce error message

[Austin Matzko]

Running the 8-25 nightly build, when I create a new post (not using the 
WYSIWYG) with an image that's linked to another image, such as the following

<a 
href="http://i.a.cnn.net/cnn/2005/TECH/ptech/08/24/sony.psp.reut/story.sony.psp.jpg"><img 
src='http://i.a.cnn.net/cnn/2005/TECH/internet/08/25/hackers.china/top.hacker.new.jpg' 
  /></a>

(In real life you might want to do this with a thumbnail)

upon pressing "publish" I get this error:

Warning: Cannot modify header information - headers already sent by (output 
started at /home/httpd/. . . /wp-includes/comment-functions.php:516) in 
/home/httpd/. . . /wp-admin/post.php on line 58

If the link isn't to an image, the problem doesn't appear.

Any ideas?
