If you are using a custom error handler (if not, you probably will be soon), you need to register it with the front controller:

$front = Zend_Controller_Front::getInstance();
$front->registerPlugin(new Zend_Controller_Plugin_ErrorHandler(array(
    'module'     => 'error',
    'controller' => 'error',
    'action'     => 'error'
)));

This means you have a module, a controller and action all called 'error'. If you don't have a custom error controller yet, google it or have a read through http://www.thedeveloperday.com/custom-profiler-for-live-environments/
