ajax_render() uses array_merge_recursive() to merge the JS settings, as opposed to drupal_array_merge_deep_array() used in drupal_get_js(). When a module (mistakenly?) adds the same settings object twice or more (seen in Openlayers), ajax_render() fails to merge duplicate values for the same keys, producing arrays instead. This is different from drupal_get_js(), which correctly merges duplicate values into one.
The attached patch fixes the issue.
