Comment (by webstract):

 There are numerous people getting this errors from themes and plugins...

 parameter-1-to-be-string?replies=17

 In my case it was this function. `$atts` is an array but gets passed to
 `make_more_shortcodes($atts)` which runs `do_shortcode()` - this was
 created for nested shortcodes.
 {{{
 add_shortcode('action', 'sc_action');
 function sc_action($atts, $content=null) {
         $atts = make_more_shortcodes($atts);
         extract(shortcode_atts(array(
                 'name' => 'scroll_form',
                 'text' => 'click here to schedule'
         ), $atts));

         if($name == 'scroll_form') $anchor = '#bigOffer';

         return '<a href="'.$anchor.'">'.$text.'</a>';
 }
 }}}
