Can't upload to google docs from php 400 error!

Question

Hi guys I'm trying to upload to google docs on a google apps account using the following code - I'm using zend framework:

function getGoogleClient($s = '')
{
  $service = Zend_Gdata_Docs::AUTH_SERVICE_NAME; 

  $user = 'aaaaa';
  $pass = 'aaaaa';

  $httpClient = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);

  return $httpClient;
}

function uploadDocument($docs, $html, $originalFileName, $temporaryFileLocation) {
    $fileToUpload = $originalFileName;
    if ($temporaryFileLocation) {
        $fileToUpload = $temporaryFileLocation;
    }

    $newDocumentEntry = $docs->uploadFile($fileToUpload, $originalFileName, null, Zend_Gdata_Docs::DOCUMENTS_LIST_FEED_URI);

}



$client = getGoogleClient();
$docs = new Zend_Gdata_Docs($client);
$ls = uploadDocument($docs, true, $file->filename, $file->tmp_name);

BUt I keep getting this error - whats wrong here :(

Expected response code 200, got 400 Inconsistent repeating query parameter
