XmlSerializer for type in signed assembly throws

Problem: If TypeMock is initialized and an XmlSerializer construction is attempted for a type in a signed assembly, the construction will fail and throw due to a typeloading error.

TypeMock v 3.5.1.
.NET fwk 1.1

using System;
using System.Xml.Serialization;
using TypeMock;
using SignedAssemblyCode.AnyType;

public class Class1
{
   public static void Main()
   {
      MockManager.Init();
      XmlSerializer serializer2 = new XmlSerializer( typeof(SignedAssemblyCode.AnyType) );
      MockManager.Verify();
   }
}

The namespace SignedAssemblyCode is imported from another assembly SignedAssembly, which is signed.

To get this to work:
* Remove signing of assembly
* Remove MockManager.Init

Consequence: Any tests that use XmlSerializers for signed assemblies will fail.

It seems very coincidental but hopefully knowledge of typemock internals may make sense of this behavior.
