Object of class stdClass could not be converted to string

When using ubercart, i came across this issue which seems to have an issue converting an object into a string.

* recoverable fatal error: Object of class stdClass could not be converted to string in /var/www/drupal/sites/all/themes/orange/template.php on line 212.

Heres the code

208    foreach ($attributes as $attribute => $data) {
209      if (is_array($data)) {
210        $data = implode(' ', $data);
211      }
212      $items[] = $attribute .'="'. $data .'"';
213    }

replacing it with this seems to do the trick:

208    foreach ($attributes as $attribute => $data) {
209      if (is_array($data)) {
210        $data = implode(' ', $data);
211      }
212      if (is_string($data)) {
213        $items[] = $attribute .'="'. $data .'"';
214      }
215    }

Another on the ubercart forums seems to confirm this fixes the issue as well.
