Uploading file with Youtube API v3 and PHP

Question

I'm trying to upload a file to youtube using the new api v3. Here's what I do...

public function upload(){

    if(isset($_FILES['userfile'])) {

        $snippet = new Google_VideoSnippet();

        $snippet->setTitle("Test v3");
        $snippet->setDescription("First upload using api v3");
        $snippet->setTags(array("api","v3"));

        $video = new Google_Video();
        $video->setSnippet($snippet);

            $response = $this->googleapi->youtube->videos->insert(
                "status,snippet",
                $video,
                array('data' => $_FILES['userfile']['tmp_name'])
                );

            var_dump($response);

  }else{
    $this->load->view('youtube');
  }
}

The response is empty, because io/Google_REST.php throws

'Undefined index: errors' at line 70

which is within decodeHttpResponse(),

however, a dump from the actual response of Google_Client::$io->makeRequest() returns the following...

object(Google_HttpRequest)#31 (10) { ["batchHeaders":"Google_HttpRequest":private]=>  
array(4) { ["Content-Type"]=>  string(16) "application/http" ["Content-Transfer-Encoding"]=>

Any help moving forwards with this would be greatly appreciated.

Read example between "this is the work in action!" and "end Work!":

<?php
@session_start();

if(!isset($_SESSION['google']))
    $_SESSION['google'] = array('state'=> null, 'token'=> null);

#include core google
