ERROR include PHP in template

[justoverclock]

hi all, i have some problem, i need to include an external php file in my template (called Justwhite)

i've create this plugin

ob_start();
include('inclusion/inclusion.php');
$includedphp = ob_get_contents();
ob_end_clean();
vB_Template: preRegister('ad_global_below_navbar',array('includ e dphp ' => $includedphp));


but i get an error??

Fatal error: Call to a member function query_first_slave() on a non-object in /forum/includes/class_bootstrap.php on line 894


why?
