How to view Silverlight traffic in Safari Web Developer?

I'm running a Silverlight application in my browser. The app communicates to a web server over HTTPS. I want to see the communication between the app and the webserver. Now when I open Web Developer I can see the requests being made. However, when I try to inspect the response from the webserver, a spinner is shown and it stays like that. How can I view the response in Safari 7?
