If the wrong session is used, it is because the session_name is wrong. The session name is set in Mage_Core_Model_Session_Abstract_Varien::setSessionName()
.
But after a look on the Stacktrace, I have no idea, why overwriting _construct
or even __construct
should be a problem here:

class MyCompany_MyModule_IndexController extends Mage_Core_Controller_Front_Action { protected $customerSession; public function _construct() { $this->customerSession = Mage::getSingleton('customer/session); } public function indexAction() { ... } ... }
then Magento creates a new customer session and everything that is loaded by this controller uses this session. I didn't call the parent _construct because this does nothing.
