2.2/develop

Hi..
I set up on my localhost of pyro cms encountered an error;

![problem](https://f.cloud.github.com/assets/2537198/2048564/c5218a88-8a4b-11e3-8b85-f47e750df84a.jpg)

$this->user_stream 			= $this->streams_m->get_stream('profiles', true, 'users');
$this->user_stream_fields 	= $this->streams_m->get_stream_fields($this->user_stream->id);

In the above line seems to be a problem.
Unfortunately, I don't know php. therefore relevant to the subject on the internet, even though I did not find troubleshoot support. so I had to write here.
Thanks. Regards.
