+This seems to be a runtime bug.
+I've created this test case:
+---
+using System;
+using System.Runtime.Remoting;
+
+[Serializable]
+class Test
+{
+	static void Main ()
+	{
+		AppDomain domain = AppDomain.CreateDomain ("hola");
+		ObjectHandle oh = domain.CreateInstance (typeof
+(Test).Assembly.FullName, typeof (Test).FullName);
+		oh.Unwrap ();
+		domain = AppDomain.CreateDomain ("hola2");
+		oh = domain.CreateInstance (typeof (Test).Assembly.FullName, typeof
+(Test).FullName);
+		oh.Unwrap ();
+	}
+}
+----
+
+if i run it like 'mono remoting.test.exe' it says:
+Unhandled Exception: System.NullReferenceException: A null value was
+found where an object instance was required
+
+however, if i do 'mono --share-code remoting-test.exe' it works.
