Comment (by ps2602):

 For some reason, there are a quite a few plugins that output white space
 which breaks xml parsing in all browsers.  I keep coming across this
 problem in both ms-files.php and now the send method of the
 WP_Ajax_Response class so I just added ob_clean to the method in order to
 prevent plugins from being able to inadvertently break functionality in
 wordpress.  I read up on ticket #14730 and I understand the viewpoint that
 ob_clean should not be used to cover the mistakes of plugin authors.
 However, finding unnecessary output in a plugin and contacting the author
 every time I come across this issue (which seems to happen often) seems
 counter-productive when users can be protected from such mistakes with a
 one-liner.
