Balance Sheet does not total Fund Value correctly

[Brendan Simon]

I have generated a Balance Sheet report and the balance/total of some
parents account do not match what is in the accounts register.

Eg. I have the following asset accounts (for a managed fund).

+ Man-OM-IP-3AHL
    . Man-OM-IP-3AHL-Cash
    . Man-OM-IP-3AHL-Shares (FUND)

The "Shares" account is of type Mutual Fund and has 5000 shares.  The
shares were purchased at $1.00 and are valued at $1.0439 (as of
30-Jun-2010).  I have used the Price Editor to set this value for this
date for OMIP3AHL security.

My Accounting period is set from 1-Jul-2009 to 30-Jun-2010.

In the Accounts register, the Balance and Total of the parent account
(Man-OM-IP-3AHL) is $5,219.50  (which seems correct ... 5,000 x $1.0439
= $5,219.50)

However, my Balance Sheet report has the following.

    MyCompany Balance Sheet 2010-06-30

    Man-OM-IP-3AHL                         5,000 OMIP3AHL    $5,000.00
        Man-OM-IP-3AHL-Shares                  5,000 OMIP3AHL    $5,000.00
        Man-OM-IP-3AHL-Cash                  $0.00                    
    Total Man-OM-IP-3AHL                         $5,000.00

As you can see the balances/total are incorrect.  They should be
$5,219.50 (the same as the accounts register).

Is this a bug ... or a something I haven't configured for reports perhaps ??

I'm using GnuCash 2.4.3 on OS X 10.6.6 (Intel)

Thanks, Brendan.
