Ran a debug log in 11172, tried to purchase it (in Opera), got a "Connection closed by remote server" error for the address http://127.0.0.1:60080/shop.php in the browser, and only line in the debug log is
Code:
class net.sourceforge.kolmafia.request.RelayRequest
EDIT: I was already at the tent when I started running the log. If the code of the tent itself is germane, then that's why it's not in my debug log.
