warning in content_copy.module

If there are no groups defined for the content type you want to copy you'll get the following warning:

warning: Invalid argument supplied for foreach() in
*/sites/all/modules/cck/modules/content_copy/content_copy.module on line 193.

because of argument

 $form_values['groups'] 

is a:0:{} is no array

wrapping the loop with

if(is_array($form_values['groups'])){
	    foreach ($form_values['groups'] as $group) {
	      $group_state = array('values' => array('group_name' => $group));
	      drupal_execute('fieldgroup_edit_group_form', $group_state, $content_type, $group, 'edit');
	    }
}

did it.
