Hi Dean, Did you ever get this resolved? If not, could you submit a bug report to http://bugzilla.xamarin.com (preferably with a sample test case) so that someone can look deeper into this issue? Unfortunately, like you, I'm not seeing anything obviously wrong in the code snippet you provided.
Thanks!
