How to use Python SecretStorage with GObject.timeout_add - Gtk3

I try to use SecretStorage in two Python processes, but when I try to update my Gtk.Window, I get this message most of the time:

RuntimeError: unable to initialize SecretService: did not receive a Reply. Possible reasons: the remote application did not send a response, the message bus security policy blocked the response, the response timeout expired, or the network connection was broken.

Both started with multiprocessing.Process , this works:

def get_data(self):
    p1 = Process(target=P1().update_database)
    p1.start()
    p1.join()
    p2 = Process(target=P2().update_database)
    p2.start()
    p2.join()

The problem is that it blocks my Gtk interface, the window is locked, other buttons are not available.

Because of this, I also used threading.Thread

def on_get_data_button_clicked(self, widget):
    thread = Thread(target=self.get_data)
    thread.start()

, , .

, Gtk.Spinner-Button

def on_get_data_button_clicked(self, widget):
    thread = Thread(target=self.get_data)
    thread.start()
    GObject.timeout_add(200, self.manage_spinner, thread)

def manage_spinner(self, thread):
    if thread.is_alive():
        return True
    else:
        self.sync_spinner.stop()
        return False

, :

RuntimeError: SecretService: . : , , , .

SecretStorage :

def get_key(self, key_name):
    bus = secretstorage.dbus_init()
    collection = secretstorage.get_default_collection(bus)
    if collection.is_locked():
        collection.unlock()
    items = collection.get_all_items()
    for item in items:
        if item.get_label() == key_name:
            return item.get_secret()
