Stefan is quite right, you are overriding the default session resource which makes use of those application options.

If you want to define your own _initSession() method and still access those options use something like:

protected function _initSession() 
{
    $options = $this->getOptions();
    $sessionOptions = array(
        'save_path' => $options['resources']['session']['save_path']
    );    
    Zend_Session::setOptions($options);
    Zend_Session::start();
}

    protected function _initSession()
{
    $config = array();
    $config['db'] = array('adapter'=>'PDO_SQLITE',
                     'params' => array('dbname'=> ROOT.'/data/tmp.db3')

                    );
    $config['SaveHandler'] = array(
        'name'    => 'sessions', //table name as per Zend_Db_Table
        'primary' => array(
            'id',   //the sessionID given by PHP
            'path', //session.save_path
            'name', //session name
        ),
        'primaryAssignment' => array(
            //you must tell the save handler which columns you
            //are using as the primary key. ORDER IS IMPORTANT
            'sessionId', //first column of the primary key is of the sessionID
            'sessionSavePath', //second column of the primary key is the save path
            'sessionName', //third column of the primary key is the session name
        ),
        'modifiedColumn' => 'modified', //time the session should expire
        'dataColumn'     => 'data',     //serialized data
        'lifetimeColumn' => 'lifetime', //end of life for a specific record
    );

    $config['lifetime'] = 60*60*24*30;

    $config['options'] = array (
                          'bug_compat_42' => '',
                          'bug_compat_warn' => '',

                          'cookie_lifetime' => $config['lifetime'],
                          'cookie_path' => '/',
                          'cookie_secure' => '0',
                          'entropy_file' => '',
                          'entropy_length' => '0',
