Bug in Custom Fields query

There is a bug in the paging through custom fields

The current code is:

for( $page = 0; $page < $pages; $page++ ) {
					$current_row = 0;
					$start = $page * $page_size;
					$end = $start + $page_size;
					$pmquery = "SELECT * FROM $wpdb->postmeta WHERE meta_value <> ''";

The query in $pmquery does not include the necessary limit. That line should be:
$pmquery = "SELECT * FROM $wpdb->postmeta WHERE meta_value <> '' LIMIT {$start}, {$page_size}";

Without that, the entire table is repeatedly looped over rather than paged through.
