Horcrux hidden via Fidelius Charm ?

Do ya think Voldemort could've used the Fidelius Charm to hide the
location of a horcrux?

Here's the text I've got about the Fidelius Charm:
"An immensely complex spell involving the magical concealment of a
secret inside a single, living soul. The information is hidden inside
the chosen person, or Secret-Keeper, and is henceforth impossible to
find -- unless, of course, the Secret-Keeper chooses to divulge it"
(PoA, Chapter 10)

The major snag I see is that the Fidelius Charm is like a buddy
system, and Voldemort isn't a team player.  However:

"When a Secret-Keeper dies, their secret dies with them, or, to put it
another way, the status of their secret will remain as it was at the
moment of their death. Everybody in whom they confided will continue
to know the hidden information, but nobody else." -- JKR website

So... Voldemort and Secret-Keeper X do the Fidelius Charm to hide the
location of a horcrux.  (X wouldn't even have to know that it's a
horcrux.  Knowing it's a locket/wand/cup/dragon/door knob would be
enough, right?)  Voldemort immediately kills X, before X even has the
chance to divulge the secret to anyone.  The secret (and the horcrux)
remain hidden for eternity.

Oh my.  Oh no...

(I did a crude search on this subject and found nothing.  If it's been
discussed before, I'd love to know where to find the thread.  Thanks!)
