Pending Calls and Asynchronous functions

Hello folks,
I have the following calls:
reply = dbus_connection_send_with_reply(conn, msg, &call,
timeout_ms);
if (reply == TRUE) {
dbus_pending_call_set_notify(call,
callback,
pending,
NULL);
}
So I get a reply from the other end (very quickly) and before a pending
function can get set in dbus_pending_call_set_notify.
And thus when _dbus_pending_call_complete is called I don't get the callback
because pending->function is NULL.
This is a race condition and I hit it 50 % of the times depending on how
loaded the system is.
Is there a better way to set the pending call ? Am I using it wrongly ?
Thanks
Jaikumar
