Account Voucher Credit invoice payment error

[Mike Lindsay]

I installed account_voucher_credits_us version 6.1.1.20? to a test database containing my data (Full list of installed modules at the end).

OpenERP 6.1 server running on Ubuntu 11.xx

1. Create a New Sales Order.
2. Create Invoice from SO.
3. Apply a payment, the following error will happen.
4. I expected to apply a payment, not generate an error.
