 the default args for wp_dropdown_categories produce an empty select box
 when using wp_dropdown_categories for a taxonomy for which there are no
 terms.  I produced this both w/ the filters on the edit.php screen
 (restrict_manage_posts) and on the front end in my theme.  I presume this
 case never occurs with post categories as there is always Uncategorized.

 {{{
 $args = array(
     'show_option_none'   => ,
     'taxonomy'           => 'featured',
     'hide_if_empty'      => false );
 }}}


 lines 340-343 in wp-includes/category-template.php are


 {{{
 if ( ! $r['hide_if_empty'] || ! empty($categories) )
                 $output = "<select name='$name' id='$id' class='$class'
 $tab_index_attribute>\n";
         else
                 $output = '';

 }}}

 so in a taxonomy that has no terms, the $categories variable is indeed
 empty, but the default arg is false, so the ! $r['hide_if_empty']
 condition is satisfied and you get the opening of the select input, but
 you don't get any options therein (since they don't exist.  and by
 default, you don't get any notice of such.
