Where/when does the NRE happen? Is it in Xamarin Studio or in your app? Do you have a stack trace?

I suspect this root issue was found a long time ago, but it's status was never updated.

If you are still experiencing this issue please provide all the requested information and re-open the bug report. Thanks!
