NServiceBus IHandleTimeouts throws SagaNotFoundHandlers

Question

I am trying to use the NServiceBus 3.0 ITimeoutState and IHandleTimeouts feature in my Saga. I have the following code snip. The following code working fine without any issue on NServiceBus.3.0.0-rc5. But, when i updated the DLLs with any version > 3.0.0 the saga timeout is not working as expected and it is throwing the following warning!

2012-04-05 09:15:26,267 [Worker.5] INFO NServiceBus.Sagas.Impl.SagaDispatcherFactory [(null)] <(null)> - Could not find a saga for the message type SomeNameSpace.MySagaTimeout with id 9496c29e-f745-4ada-8212-99e47324922b\20920. Going to invoke SagaNotFoundHandlers.

Please help me to resolve this issue.

The TimeoutMessage:

public class MySagaTimeout : ITimeoutState
{
    public InputMessage1 Source { get; set; }
}

The Saga Code:

public class BrandMerchandisingRoot : Saga<MySagaState>,
                                          IAmStartedByMessages<InputMessage1>,
                                          IHandleTimeouts<MySagaTimeout>,
                                          IHandleMessages<MySagaTimeout>
{
      public void Handle(InputMessage1 message)
      {
        RequestUtcTimeout(5.Seconds(), new MySagaTimeout {Source = message});
      }

      public void Timeout(MySagaTimeout state)
      {
        //some other code here
      }

      public void Handle(MySagaTimeout message)
      {
         Timeout(message);
      }
}

The Configuration:

Configure.With()
.StructureMapBuilder(ObjectFactory.Container)
.RunTimeoutManager()
.UseInMemoryTimeoutPersister()
.MsmqSubscriptionStorage()
.Sagas()
.UnicastBus();

NOTE: I am using my own saga persister and I have the implementation for IFindSagas<MySagaState>.Using<MySagaTimeout>
