----------------------------+-----------------------------------------------
 I am using this code in my theme to query the posts.
 {{{
 <?php
 wp_reset_query();
                         query_posts(array(
                                                         'cat' => 7,
                                                         'orderby' =>
 "date",
                                                         'order' => "DESC",
                                                         'post__not_in' =>
 array(25,26,27),
                                                         'showposts' => 0,
                                                         'nopaging' => true
                                                 ));
 ?>
 }}}

 In the 2.6 version works fine this, when a made de Update to 2.7 the theme
 isn't loading.

 After few hours debugging, I found the misterious cause.

 wp-includes.php (line ~ 1328)
 {{{
 <?php
 if ( empty($qv['cat']) || ($qv['cat'] == '0') ) {
                                 $this->is_category = false;
                         } else {
                                 if (strpos($qv['cat'], '-') !== false) {
                                         $this->is_category = false;
                                 } else {
                                         $this->is_category = true; //Fails
 here
                                 }
                         }
 ?>
 }}}

 When the variable $this->is_category is set to TRUE, the script
 "mysteriously" fails, any thing after the line doesn't load.

 What I need to do to this works?

 Julio
