title: NuGet "Failed to generate binding redirects for My Project" with error "Object reference not set to an instance of an object."
body: <p>On several different packages like SquishIt and DotNetOpenAuth i get an error saying:</p>
  
  <blockquote>
    <p>Failed to generate binding redirects for 'MyProject'. Object reference not set to an instance of an object.</p>
  </blockquote>
  
  <p>I've seen a lot of post about other people having problems with "binding redirects" but not found a single reference to this problem combined with "Object reference not set to an instance of an object.".</p>
  
  <p>What exactly is NuGet trying to do at this stage? Does it try to update the binding redirects in Web.Config? Could i have some issue with my Web.Config? How can i go about debugging this?</p>
  
  <p>I shall say that this does not happen in a "clean" project. </p>
