 {{{
 <?php
 require_once('wp-config.php');
 update_option('blog_public', '1');

 function return_zero($option_val) {
         return 0;
 }

 add_filter('pre_option_blog_public', 'return_zero');

 var_dump(get_option('blog_public'));
 ?>
 }}}

 Expected result is:

 {{{
 string(1) "0"
 }}}

 Actual result is:

 {{{
 string(0) "1"
 }}}

 Patch is on the way.
