"All file extensions allowed" conflicts with Drupal 7 extensions management

In the "imce_upload_submit()" function of "imce.page.inc", the $validators management doesn't fit the Drupal 7 "file_save_upload()" file extensions management rules : in IMCE the joker for "all extensions allowed" is "*", but in "file_save_upload()" it is an empty array. Because of that, event if all extensions are allowed in IMCE, not all file extensions can be uploaded (".swf", for example).
The addition of

 if( ! isset($validators['file_validate_extensions']) && $imce['extensions']=='*' )
    $validators['file_validate_extensions'] = array();

after "$validators = array('imce_validate_all' => array(&$imce));", at line 283 of "imce.page.inc" solves the problem.
