 I'm getting a white screen on my main WordPress site when I Publish a post
 since starting to use 2.7.

 My server error logs contain the following that matches time wise for
 every white screen I've seen:

 PHP Catchable fatal error:  Object of class WP_Error could not be
 converted to string in /home/prescrib/public_html/wp-includes/comment.php
 on line 1264

 I have disabled all plugins and still get this error. (Strangely, this is
 not reproducible on my localhost dev WordPress so there may be some server
 settings involved too.
