 I added two similar custom key from my theme and a plugin with
 postmeta_form_keys filter.
 but now display both of theme in custom-fields name's select box (custom-
 fields metabox - post.php or post-new.php)
 I think is better to unique $keys before options are printed.

 wp-admin/includes/template.php
 line ~730

 before:
 foreach ( $keys as $key ) {

 after:
 $keys = array_unique($keys);
 foreach ( $keys as $key ) {
