[shortcodes] problem with $atts

Obviously something here is not correct but I just cant see it any help appreciated.

The code is executing as it should accept that immediately after entry to ABNet_handler_blogs_newest(), inspection is showing a null terminated string for $atts. Why would the params not be passed to the handler?

[netblogsnewest count=2 total=true]

add_action("after_setup_theme", "ABNet_handler_blogs_newest", 15);

add_shortcode('netblogsnewest','ABNet_handler_blogs_newest');

function ABNet_handler_blogs_newest( $atts ) {
    if( !is_multisite() ) return false;

    extract( shortcode_atts( array(
                'count' => '',
                'total' => '',
           ), $atts )
     );
     return ABNet_output_blogs_newest($count, $total);

}
