'Serialization of 'SimpleXMLElement' is not allowed' - hybridauth

Question

I've changed around the path structure for HybridAuth quite a bit, all of the HybridAuth files are in a login directory.
require_once('login/Auth.php');
$auth = new Hybrid_Auth(self::$settings['auth']);
Where self::$settings['auth'] is this json file
{
"debug": 1,
"database": {
"driver": "mysql",
"host": "localhost",
"port": 3306,
"name": "ws_db",
"username": "root",
"password": "",
"charset": "utf8"
},
"auth": {
"base_url": "http://localhost/login/process",
"providers": {
"Twitter": {
"enabled": true
},
"Google": {
"enabled": true,
"keys": {
"id": "",
"secret": ""
}
},
"Facebook": {
"enabled": true,
"keys": {
"id": "",
"secret": ""
},
"trustForwarded": false
},
"Steam": {
"enabled": true
}
},
"debug_mode": true,
"debug_file": "auth.txt"
}
}
I have not yet acquired keys for the providers I intended to use (is that possibly why this is happening?). I tried to login with Steam to test that it was working since it was the only provider that didn't require me to get keys.
$_SESSION['user'] = $auth->authenticate('Steam');
I was correctly redirected to a Steam login page however upon clicking Login I received the above error.
Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement' is not allowed' in login\Auth.php:153 Stack trace: #0 login\Auth.php(39): Hybrid_Auth::initialize(Array) #1 index.php(83): Hybrid_Auth->__construct(Array) #2 index.php(6): Site::main() #3 {main} thrown in login\Auth.php on line 153
I thought it possibly had something to do with this line:
Hybrid_Logger::debug( "Hybrid_Auth initialize. dump used config: ", serialize( $config ) );
because that is the only line that I see serializing something but commenting that out didn't seem to work. Line 83 in my index.php is the initialization of Hybrid_Auth.
$auth = new Hybrid_Auth(self::$settings['auth']);
I can't seem to figure out what is going wrong with this though. Since that line of code is run when attempting to login and only causes a problem when returning from the Steam authorization page.
Here is the information that was output into auth.txt, I removed some information.

This was an issue with the Steam provider and was fixed in a commit you can download the fixed steam provider from the github repo.
