Hello, 

After making a MVC framework i found that it was impossible to passe some arrays to the template, it was my mistake (function only took strings and not arrays) yet it keeped making apache to seg fault, that is not normal. Check the code posted.

Reproduce code:
---------------
-----file /classes/AdminHelpers.php
class AdminHelpers
{
    public static function CacheRegionList($db)
    {
       $sth = $db->prepare('SELECT `id_region`,`reg_nom` FROM `gps_region`');
    }
}

-----file /controllers/admin/equipes.php
class Controller_Equipes extends Controller_base
{
    public function Update()
    {
        parent::SetNavigation('admin');
        parent::Navigation();
        AdminHelpers::CacheRegionList(); // Note the missing argument
    }
}

Expected result:
----------------
Missing argument 1 for function CacheRegionList...

Actual result:
--------------
Apache segfault.
