Please describe the problem:
The mortgage druid is completely broken for me (and has been since this feature first appeared in 1.8).

I enter the parameters for my home mortgage, and the review shows ridiculous payment amounts and no principal or interest.

Steps to reproduce:
1. Start mortgage druid.
2. Enter the following on Loan info page
amount: 269000.00
rate: 4.990%
fixed
start: 4/03
length: 360
months remaining: 321 (automatic)

3. Options page:

pay taxes
pay insurance

4. Repaymnet page:

pay from a bank account
principal to a liability account
interest to an expense
frequency: monthly on the 5th

5. Tax page:
pick an amount ($500), direct to an expense account
part of payment transaction

6. Insurance page:
pick an amount ($100), direct to an expense account
part of payment transaction



Actual results:
On the review page, I see amortization for the current year.  But, each month's line is identical:

date       paymnt      principal    interest    taxes    insurance
XX/05/06   156,664.00                           500      100


Expected results:
I expect to see reasonable payments with principal and interest calculated.

Does this happen every time?
yes

Other information:
This is gnucash 1.9.6-3 in debian testing.

The exact same problem existed for me in 1.8.X.  The money file was created under 1.8
