After deep investigation, the problem is only when Piwigo combines JS/CSS.
The bug comes from admin/themes/default/fontello/css/animation.css loaded by admin/themes/default/template/include/add_album.inc.tpl (to animate a vector icon instead of a animated GIF). The minification of animation.css breaks CSS parsing and following scripts are not correctly executed, including Admin Tools scripts.
The break of AdminTools is just the visible effect of problematic animation.css.
and also on the Batch Manager.
