use as formatter in Views - nothing shows

I use galleryformatter often enough, but for the first time inside Views.
I've selected galleryformatted as formatter for image field and it returned nothing.

Fix:
renderable array generated properly, problem with returning value
galleryformatter.module
line: 375

/**
 * Implements hook_field_formatter_view().
 */
function galleryformatter_field_formatter_view($entity_type, $entity, $field, $instance, $langcode, $items, $display) {
  ...
  //return $element;
  return array($element); // Return array with $element instead
}
