Ninject + MVC3 = InvalidOperationException: Sequence contains no elements

I created a new MVC3 project, hit F5, saw the sample page.

Then I used NuGet to get the Ninject.MVC extension. I modified my global.asax according to the Ninject documentation, How To Setup an MVC3 Application:

public class MvcApplication : NinjectHttpApplication
{
   public static void RegisterGlobalFilters(GlobalFilterCollection filters)
   {
       filters.Add(new HandleErrorAttribute());
   }

   public static void RegisterRoutes(RouteCollection routes)
   {
       routes.IgnoreRoute("{resource}.axd/{*pathInfo}");

       routes.MapRoute(
           "Default", // Route name
           "{controller}/{action}/{id}", // URL with parameters
           new { controller = "Home", action = "Index", 
               id = UrlParameter.Optional });
   }

   protected override IKernel CreateKernel()
   {
       var kernel = new StandardKernel();
       kernel.Load(Assembly.GetExecutingAssembly());
       return kernel;
   }

   protected override void OnApplicationStarted()
   {
       base.OnApplicationStarted();

       AreaRegistration.RegisterAllAreas();
       RegisterGlobalFilters(GlobalFilters.Filters);
       RegisterRoutes(RouteTable.Routes);
   }
}

Now when I run the app, I get the yellow screen of death with the following exception:

InvalidOperationException - Sequence contains no elements.

at System.Linq.Enumerable.Single(...)

at Ninject.Web.Mvc.Bootstrapper.Initialize(...) line 67.

And sure enough, line 67 of that file calls .Single(), thus throwing the exception.

What am I doing wrong?
