gnc-prices tells GnuCash that my T-bills have quintupled in value

[Seth Gordon]

I took advantage of the snow day to move the family's accounting from
a forest of StarOffice spreadsheets to GnuCash (1.4.10 on a Red Hat
Linux 6.2 system).

First, I want to congratulate the developers for all the hard work
they devoted to making this excellent program.

Second, I have a problem (or a misunderstanding) with the way
gnc-prices handles mutual funds.  I had an account configured like
so:

Account name: Vanguard money market
Currency: USD
Security: VMPXX
Account type: Mutual Fund
Price quote source: Vanguard

The first line of the register for the account looks something like
this:

Date: 2001-01-16
Description: Adjust Balance
Transfer: Equity
R: c
Bought: X
Price: 1
Value: X
Total shares: X
Balance: X

(where X is, of course, the number of dollars in the account at that
time)

After installing all the appropriate Perl modules, I ran gnc-prices,
and got the following output:

Opening file gorpel.xac
Mutual funds: unknown. skipping...
Vanguard money market: using VANGUARD
Vanguard money market: VMPXX VANGUARD TREAS   last price = 5.10 at 3/6/2001
Stock: unknown. skipping...
VA Linux Systems: using YAHOO
VA Linux Systems: LNUX VA LINUX SYSTMS  last price = 4.0625 at 3/6/2001

When I reopened the file in GnuCash, I found this line added to the
register:

Date: 2001-03-06
Description: Price
Price: 5.1
[and so on]

...and the running balance in the Vanguard register had quintupled.  I
doubt that US Treasury securities are doing *that* well on the market.

Is there a problem with the way GnuCash (or Finance::Quote) adjusts
mutual-fund values, or is there a problem with the way I set up the
account?
