Unsupported operand types on line 269

I'm running the latest cvs version for everything on PHP 5.0.4 and I get this error when trying to set a reminder

Fatal error: Unsupported operand types in C:\Web Sites\drupal-head\modules\remindme\remindme.module on line 269

which is this line
return array(0 => t('Disabled') + drupal_map_assoc(array(900, 1800, 3600, 10800, 21600, 32400, 43200, 86400, 172800, 259200, 604800, 1209600, 2419200), 'format_interval'));
