LinkedIn callback not working for certain URLs (using Zend Framework)

Question

LinkedIn doesn't seem to like the idea of redirecting back to my test site.

This code directs me to the LinkedIn confirm page without any problems: (This is pretty much a boilerplate example using Zend's OAuth)

$options = array(
    'version'               => '1.0',
    'callbackUrl'           => 'http://dev.local/',
    'requestTokenUrl'       => 'https://api.linkedin.com/uas/oauth/requestToken',
    'userAuthorizationUrl'  => 'https://api.linkedin.com/uas/oauth/authorize',
    'accessTokenUrl'        => 'https://api.linkedin.com/uas/oauth/accessToken',
    'consumerKey'           => [api],
    'consumerSecret'        => [secret]
);

$consumer = new Zend_Oauth_Consumer( $options );

// Start Requesting a LinkedIn Request Token
$token = $consumer->getRequestToken ();

// Store the LinkedIn Request Token
$_SESSION ['REQUEST_TOKEN'] = serialize ( $token );

// Redirect the Web User to LinkedIn Authentication  Page
$consumer->redirect ();

However if my callback is http://dev.local/ it does not redirect, but if I specify a valid domain (like http://www.google.com) it redirects with no problem.

This behaviour happened recently (it was working fine until about a month ago). This is obviously a serious pain since I need to deploy code to be able to test anything.

Is this a problem people have experienced and has anyone found a way to get around?

it seems this is because LinkedIn changed their API, specifically how the api interacts with Oauth:

On the technical side, we've borrowed the OAuth 2.0 concept of the "scope" parameter and incorporated it into our OAuth 1.0a and JS Authentication flows.

Seems other apps, plugins and libraries are experiencing some difficulty with this as well.
