Ninjauth and vk.com - Required option not passed: access_token

[sashbb]

Hi.
Facebook/google/twitter authentication works fine.

But when I try to configure authentication via russian socnetwork vk.com, I get broken $options array and an error:

OAuth2\Exception [ Error ]: Required option not passed: access_token Array ( [{"access_token":"54346afb097c25dsd459c36029ae59f299d654349c259c360fd49554c4f985175f3a0d11","expires_in":86400,"user_id":17234230490}] => )
PKGPATH/oauth2/classes/token/access.php @ line 50

I use this provider class:
https://github.com/Maxlab/fuelphp/blob/master/fuel/packages/oauth2/classes/provider/vkontakte.php

I will be grateful for any help.
