Ubuntu with Gnome-keyring 2.92.92.is.2.31.91-0ubuntu4 and libgnome-keyring0
2.31.92-0ubuntu1

When I remotely call the Unlock method on org.freedesktop.secret.Service, I got this exception
org.freedesktop.dbus.exceptions.NotConnected: Disconnected

at $Proxy2.Unlock(Unknown Source)


Here is an extract of my code:


Item item = (Item) conn.getRemoteObject(BUS_NAME, objectPath, Item.class);
try {
	secret = item.GetSecret(dbusSession);
} catch (DBusExecutionException dbee) {
        if (dbee.getType().equals(org.freedesktop.Secret.Error.IsLocked.class.getCanonicalName())) {
		List<DBusInterface> itemsToUnlock = new ArrayList<DBusInterface>(1);
		itemsToUnlock.add(item);
		Pair<List<DBusInterface>,DBusInterface> usr = serv.Unlock(itemsToUnlock);
        }
}

If the password is not locked, the GetSecret works fine.
If it is locked, the GetSecret throws a Error.IsLocked, and then the call to Unlock fails with above exception.

I also tried to unlock all passwords in the collection at once (I pass the list of locked items returned by SearchItems) and got the same error.
