Please describe the problem:
The GnuCash accounts receivable system automatically generates transactions in
accounts receivable. These transactions can be imbalanced due to roundoff errors. 

Steps to reproduce:
1. For example, create a tax table with two entries: 8% GST and 7% PST, which
are posted to two different tax payable accounts (federal and provincial, Canada). 

2. Create and post an invoice with net sales $100.78. 

3. Print an invoice for the customer.


Actual results:
The customer is billed $115.90 (his tax is shown as $15.12). In the accounts, my
sales account is credited $100.78, my federal tax account is credited $7.05, and
my provincial tax account is credited $8.06. The automatically generated
transaction is out of balance by $0.01.



Expected results:

Correct would be to round each tax separately, and add the rounded values. The
customer should be billed $115.89, not $115.90.

Does this happen every time?
Yes.
