To complete the bug description, we are using the last 6.1 openobject-
addons branch, to test this error, just make a new database with demo
data, install account_voucher, without any account plan. Set the company
to any currency other than EUR (so it won't be rate 1) and to an invoice
in another third currency and try to do a payment with any currency, the
debit and credit amount will be wrong calculated.

Title:
  [6.1] [account_voucher] exchange rate calculation is not working if
  company currency isn't rate 1

Status in OpenERP Addons (modules):
  New

Bug description:
  In the account_voucher module, the currency rate is not well
  calculated. The method that write the account move line is not
  correct. It starts at line 227 in account_voucher.py:

      def _paid_amount_in_company_currency(self, cr, uid, ids, name, args, context=None):
          if not ids: return {}
          res = {}
          rate = 1.0
          for voucher in self.browse(cr, uid, ids, context=context):
              if voucher.currency_id:
                  if voucher.company_id.currency_id.id == voucher.payment_rate_currency_id.id:
                      rate =  1 / voucher.payment_rate
                  else:
                      ctx = context.copy()
                      ctx.update({'date': voucher.date})
                      voucher_rate = self.browse(cr, uid, voucher.id, context=ctx).currency_id.rate
                      company_currency_rate = voucher.company_id.currency_id.rate
                      rate = voucher_rate * company_currency_rate
              res[voucher.id] =  voucher.amount / rate
          return res

  This should be (diff output):

           for voucher in self.browse(cr, uid, ids, context=context):
               if voucher.currency_id:
                   if voucher.company_id.currency_id.id == voucher.payment_rate_currency_id.id:
  -                    rate =  1 / voucher.payment_rate
  +                    rate =  voucher.payment_rate
                   else:
                       ctx = context.copy()
                       ctx.update({'date': voucher.date})
                       voucher_rate = self.browse(cr, uid, voucher.id, context=ctx).currency_id.rate
                       company_currency_rate = voucher.company_id.currency_id.rate
  -                    rate = voucher_rate * company_currency_rate
  -            res[voucher.id] =  voucher.amount / rate
  +                    rate = company_currency_rate / voucher_rate
  +            res[voucher.id] =  voucher.amount * rate
           return res

  
  I am posting a merge proposal with this change in a couple of minutes.

  There is also a wrong currency_amount value calculation even if you
  apply the previous patch. This wrong calculation apply to only some
  lines of the move. I will get back on this bug about this later.
