Notice: Undefined property: CRM_Core_Config::$defaultContactStateProvince in CRM_Contribute_Form_Contribution->setDefaultValues() (line 504 of CRM/Contribute/Form/Contribution.php)

When I attempt to make a contribution at:
http://example.com/civicrm/contact/view/contribution?reset=1&action=add&cid=34&context=contribution&mode=live

I receive the following error on every page in the process:
========
Notice: Undefined property: CRM_Core_Config::$defaultContactStateProvince in CRM_Contribute_Form_Contribution->setDefaultValues() (line 504 of CRM/Contribute/Form/Contribution.php)
========

I'm using CiviCRM 4.2 on PHP 5.5

I discovered that defaultContactStateProvince is not a property on CRM_Core_Config.
