I use this one and it never failed:

    function pageTitle($echo){
        $title = "";

        global $paged;
        if (function_exists('is_tag') && is_tag()) {        
            $title .= single_tag_title(__("Tag Archive for "" , 'circle'),false); 
            $title .= '" - '; 
        }
        elseif (is_archive()) {
            $title .= wp_title('',true); 
            //$title .= __(' Archive - ' , 'circle');
            $title .= __(' - ' , 'circle');

        }
        elseif (is_search()) {
        $title .= __('Search for "' , 'circle') . esc_html(get_search_query()).'" - '; 
        }
        elseif (!(is_404()) && (is_single()) || (is_page())) {
            $title .= wp_title('',true); 
            $title .= ' - '; 
        }
        elseif (is_404()) {
            $title .= __('Not Found - ' , 'circle'); 
        }
        if (is_home()) {
            $title .= get_bloginfo('name'); 
            $title .= ' - '; 
            $title .= get_bloginfo('description'); 
        }
        else {
            $title .= get_bloginfo('name'); 
        }
        if ($paged>1) {
            $title .= ' - page ' . $paged; 
        }

        if ( !$echo ) return $title;
        echo $title;
    }

Note that there are translation domains in it that you might want to change.
