A bill entered via the Vendor/New Bill system and then posted, appears in the Accounts Payable, but the "Bill" column (and the Payment column) are both empty, even though the balance column shows the proper amount. Paying the bill similarly results in a blank transaction being created (but with the balance column correct) both in the Accounts payable and the transfer account.

To reproduce:

1. Create new business accounts tree
2. Create vendor
3. Create bill for that vendor (note the incorrect entry in the Accounts payable)
4. Find the bill and pay it using the Busines->Find Bill dialogue
5. Note the incorrect entries created in the Accounts Payable and transfer account
