 It happend to me that a nginx reverse proxy did cut off all query
 parameters.
 This resulted in no CSS and JS for the WP backend / login.

 Because the request was manipulated by a (reverse-) proxy i wasn't able to
 see that the request passed to wordpress was indeed "invalid", beacuse the
 load[] parameter is required to do something meaningful.

 I want to add a small patch which checks if the load[] parameter is set
 and is formally valid.
 In the case where the load[] parameter isn't valid there should be an
 appropiate indicator that there is something wrong.
 With this I'm aiming to make it easier, for a developer or system
 administrator, to find this kind of "error".
