title: ASP.NET MVC4 Controller with OnException not working if inheriting BaseController
body: <p>I have a <code>UsersController</code>, with <code>OnException</code> (which works), but if I make the <code>Controller</code> inherit from <code>BaseController</code>, the <code>OnException</code> doesn't work, even if I put it in the <code>BaseController</code>.</p>
  
  <p>Basically I want to have all my controllers inherit from <code>BaseController</code> so I can just have one <code>OnException</code> handler there, which catches everything...</p>
