Strict warning preprocess_html.

First of all, thanks for the great theme, this is my favorite theme from two weeks!

To reproduce:
- show all errors by adding to settings.php :

error_reporting(-1);
$conf['error_level'] = 2;
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

Results:
Strict warning: Creating default object from empty value in mojo_preprocess_html() (line 15 of /sites/all/themes/mojo/inc/process.inc)
