 By creating filter for function ( in wp-includes/media.php - line 578)

 {{{
 function img_caption_shortcode($attr, $content = null) {
 }}}

 during debugging, I found the martian empty snd params !

 {{{
 $output = apply_filters('img_caption_shortcode', '', $attr, $content);
 }}}

 where we attempt to find only the two params of the function, there is
 here this empty martian param and to create the filter (add_filter) it was
 necessary to create a dummy first param for a total of 3 and so on... I
 don't find elsewhere in wp core some place where this filter is used..

 Is it possible to erase this empty param to be coherent.

 Best regards

 Michel

 NOTE :
 it is the same bizarous empty param here in line 611

 {{{
 $output = apply_filters('post_gallery', '', $attr);
 }}}
