The remoting stack hides exceptions. See
https://bugzilla.novell.com/show_bug.cgi?id=584067 where a type is being
created in another appdomain using AppDomain.CreateInstanceAndUnwrap.

NET shows a useful stack trace, but Mono shows a completely opaque remoting
messaging exception:

 System.Reflection.TargetInvocationException: Exception has been thrown by the
target of an invocation. ---> System.NullReferenceException: Object reference
not set to an instance of an object

Server stack trace:
