Undefined index: errors in google-api-php-client/src/io/Google_REST.php

[johannesnagl]

sometimes the google+ api retuns errors without setting the 'errors' key. so the code throws an error.

in relation to https://code.google.com/p/google-api-php-client/issues/detail?id=266 i would suggest the following change:

//throw new Google_ServiceException($err, $code, null, $decoded['error']['errors']);
$error_msg = $err;
if(isset($decoded['error']) && isset($decoded['error']['errors'])){
  $error_msg = $decoded['error']['errors'];
}
throw new Google_ServiceException($err, $code, null, $error_msg);
