 First of all, I'm really sorry for my previous fake report.
 This time, I have done enough search and test, and I can't find out a
 solution.
 I'm using fresh 3.2.1 installation for testing this plugin.

 http://wordpress.stackexchange.com/questions/578/adding-a-taxonomy-filter-
 to-admin-list-for-a-custom-post-type/3215

 https://gist.github.com/541505

 public param value is true.
 exclude_from_search is false

 However, it doesn't work so I have to  trace the wordpress source code.
 Here is what I find in the 177th line in wp-includes/query.php.


 {{{
 $tax_query[] = array(
         'taxonomy' => 'category',
         ******
 );
 }}}


 then,

 $this->tax_query = new WP_Tax_Query( $tax_query );

 in the 2199th line,

 {{{
 $clauses = $this->tax_query->get_sql( $wpdb->posts, 'ID' );
 }}}

 WP_Tax_Query is in wp-includes/taxonomy.php

 get_sql  -> clean_query -> transform_query invokes sql operation


 {{{
 SELECT $wpdb->term_taxonomy.******* WHERE taxonomy = 'query['taxonomy']'
 AND *****
 }}}

 however, the  {{{'query['taxonomy']'}}} is 'category' which was hardcoded
 in the 177th line in wp-includes/query.php.

 Is this a bug?
