'new Pkcs11()' fails

Hi,

in my xulrunner application, that I've compiled with the current
mozilla sources, I cannot instantiate the Pkcs11 DOM object.

This code
try {
    var Pkcs11 = new Components.Constructor("@mozilla.org/security/
pkcs11;1", "nsIDOMPkcs11");
    var myPkcs11 = new Pkcs11();
......
 throws an error at the 'new Pkcs11()' line:
error [Exception... "Component returned failure code: 0x80570015
(NS_ERROR_XPC_CI_RETURNED_FAILURE) [nsIJSCID.createInstance]"
nsresult: "0x80570015 (NS_ERROR_XPC_CI_RETURNED_FAILURE)"

Anybody can help me, please?

It's working (in DEBUG mode), compiled from the sources  with
MOZ_CO_DATE="14 Apr 2009 13:00 PDT" .


Kind wishes,
Viktor Tarasov.
