I am using Zend Debugger to debug my php application built based on the Zend Framework. Currently I am running the 1.10.6 version. When debugging my application i Get this error:

Compile Error: /var/www/Zend/ZendFramework-1.10.6/library/Zend/Loader/Autoloader.php line 36 - Cannot redeclare class Zend_Loader_Autoloader

Bu Zend Framework sadece bir hata mı yoksa benim application.php içinde bir yanlış ile ilgisi var mı?

$paths = array(

    realpath(dirname(__FILE__).'/../library'),
    '.',
);
*/


defined('APPLICATION_PATH') 
    or define('APPLICATION_PATH', realpath(dirname(__FILE__).'/../application'));
defined('APPLICATION_ENV')
    or define('APPLICATION_ENV', 'development');

set_include_path(implode(PATH_SEPARATOR, array(
    realpath(APPLICATION_PATH.'/../library'),
)));    


//require_once('Zend/Loader/Autoloader.php');   
require_once('Zend/Application.php');

$application = new Zend_Application(
    APPLICATION_ENV,
    APPLICATION_PATH.'/configs/events.ini'  
);

$application->bootstrap()->run();
