Warning: Invalid argument supplied for foreach() in conditional_fields_features_export_options()

I got this error message when trying to create a feature.

Warning: Invalid argument supplied for foreach() in conditional_fields_features_export_options() (Zeile 14 von /sites/all/modules/conditional_fields/includes/conditional_fields.features.inc).

This is the function:

function conditional_fields_features_export_options() {
  $dependencies = conditional_fields_load_dependencies();
  $entity_info = entity_get_info();
  $options = array();
  foreach ($dependencies as $type => $data) {
    foreach ($data as $dependency => $info) {
      $option = $type . ':' . $dependency;
      if (!isset($options[$dependency])) {
        $options[$option] = $entity_info[$type]['bundles'][$dependency]['label'] . ' (' . $type . ')';
      }
    }
  }
  return $options;
}

The function conditional_fields_load_dependencies(); can return "false" if there are no dependencies (?). I think this is what happens here. So I added this to check my findings:

  if (!is_array($dependencies)) {
    $dependencies = array();
  }

Message gone.

Changed the code to this:

  if (!is_array($dependencies)) {
    return (array());
  }

This code does not look good, so the patch is not good. But its late right now.

How could I do this in good coding style?
