Comment 2 for bug 785427

Forget Gross Profit, You are still calculating net profit. So because both
sum_dr and sum_cr have the potential to be incorrect, this value has the
potential to be incorrect. Follow this thinking through and now the balance
sheet too is incorrect (although another error in the way balance sheet
parser calls P&L already makes it highly likely be incorrect.
