PHP Fatal error: Unsupported operand types

Hi,

Today, I was playing with panels, and when I attempted to add a flexible layout through /admin/structure/panels/layouts/add-flexible, I got the error PHP Fatal error: Unsupported operand types in /var/www/drupal-7/sites/all/modules/ctools/plugins/content_types/token/token.inc on line 42

The offending line reads

 $token += array('description' => '');

Regards,
