Comment 24 for bug 661272

so it seems for my case that we are stuck in "case PASSWD_STATE_NEW" of io_watch_stdout, because of an error of "Authentication token manipulation error".

If i force the state to go to PASSWD_STATE_RETYPE by adding

           else if(is_string_complete (str->str, "token", NULL)) {
                /* Advance to next state */
    passwd_handler->backend_state = PASSWD_STATE_RETYPE;
                reinit = TRUE;
            }

in the if of case PASSWD_STATE_NEW of io_watch_stdout, the interface doesn't freeze, but prompt me the same error message that i had the first time, i must so retype a second time the right new password.
