facebook api appending #_=_ to my return uri [duplicate]

Question

I'm using the facebook php library to authenticate users to my app, it's working fine but for some reason facebook is appending the characters #_=_ to the end of my return uri. I read that they did this if the redirect_uri parameter wasn't set but I do have it set, in fact I'm redirected to that URL successfully after I log in on facebook.

Here's how I get the login url:

$fbLoginUrl = $fb->getLoginUrl(array(
    'scope' => 'email,publish_stream,user_birthday,user_photos,friends_photos',
    'redirect_uri' => 'http://myapp.net/auth'
));

Everything works fine it's just a cosmetic thing I guess. Can anyone help me?

Thanks in advance!

On Facebook developer blog, it was told that, if you explicitly set the redirect_uri param, you won't get the #_=_ appended to the callback uri. But this is not the case. You still get those characters even on setting redirect_url field. But that won't have any effect on your flow.
