SUPEE 7405 - Hunk #2 Failed at 43

Question

Today 2 patches were released for my Magento 1.9.1.0 CE website - SUPEE 7405 and 7616. Installing 7616 on my local dev site worked perfectly and I experienced no problems. When attempting to run 7405 I received the following output:

IT1+Liam.McArthur@IT1 MINGW32 /c/xampp/htdocs/website
$ sh PATCH_SUPEE-7405_CE_1.9.1.1_v1-2016-01-20-04-42-03.sh

Here's the function it appears to be failing on (line 43) of Observer.php:

public function actionPreDispatchAdmin($observer)
{
    $session = Mage::getSingleton('admin/session');
    /** @var $session Mage_Admin_Model_Session */
    $request = Mage::app()->getRequest();
    $user = $session->getUser();

    $requestedActionName = $request->getActionName();
    $openActions = array(
        'forgotpassword',
        'resetpassword',
        'resetpasswordpost',
        'logout',
        'refresh' // captcha refresh
    );

Is anyone else experiencing problems patching this update or does anybody have any guidance on what could be causing the issue?

UPDATE: I've noticed that the following code doesn't exist in app/code/core/Mage/Admin/Model/Observer.php. Would this indicate a previous patch has failed?

if (!$request->getInternallyForwarded()) {
    $request->setInternallyForwarded();

Answer 1

It looks like the website isn't patched for SUPEE 5344. This means that new code snippets such as `$request->setInternallyForwarded()' don't exist in the Observer.php and are making the line numbering incorrect.
