Missing module_load_include for ec_receipt_card_types()

I am using e-commerce for paypal pro functionality only, so I am directly creating receipts. When expand_credit_card in ec_receipt.module tries to call ec_receipt_card_types() it is missing the module_load_include for ec_receipt.admin.inc. For my purposes I've added the module_load_include to the beginning of expand_credit_card, this may not be the correct place though.
