Comment(by Denis-de-Bernardy):

 some code to fix it, in case there is any interest:

 {{{
         /**
          * fix_tinymce_paste()
          *
          * @param string $content
          * @return string $content
          **/

         function fix_tinymce_paste($content) {
                 if ( strpos($content, '_mcePaste') === false )
                         return $content;

                 $content = stripslashes($content);

                 do {
                         $old_content = $content;
                         $content = preg_replace_callback("~(<div
 id=\"_mcePaste\".*?>)(.*?)(</div>)~is", 'fix_tinymce_paste_callback',
 $old_content);
                 } while ( $content && $content != $old_content );

                 global $wpdb;
                 $content = $wpdb->escape($content);

                 return $content;
         } # fix_tinymce_paste()


         /**
          * fix_tinymce_paste_callback()
          *
          * @param array $match
          * @return string $output
          **/

         function fix_tinymce_paste_callback($match) {
                 $content = $match[2];

                 if ( !$content || strpos(strtolower($content), '<div') ===
 false )
                         return '';

                 $content .= $match[3];
                 do {
                         $old_content = $content;
                         $content = preg_replace("~<div.*?>.*?</div>~is",
 '', $old_content);
                 } while ( $content && $content != $old_content );

                 return $match[1] . $content;
         } # fix_tinymce_paste_callback()

 add_filter('content_save_pre', 'fix_tinymce_paste', 0);
 }}}
