setFileToSend is fail, size is 0

[dreamsxin]

$filename = '/var/www/public/data/avatar.png';
$this->response->setHeader('Cache-Control', 'max-age=3600');
$this->response->setContentType('image/jpeg');
$this->response->setFileToSend($filename);
$this->response->send();

May be Same as #821

Looks like Phalcon\Http\Response::_file property is used only in setFileToSend() in phalcon_update_property_this(this_ptr, SL("_file"), file_path TSRMLS_CC); and is never used anywhere. At least send() does not use it at all.
