Edited Issue: Messenger Bug when Assinging a Lambda Expression with a parameter to the messenger [7600]

Hi

I've a simple message which I sent with the Messenger .

Now Depending on the registration for this message I got a exception (s. below)


The following code works
```
Messenger.Default.Register<ResolveEntityValueMessage>(this, (msg)=>handleEntityValueMessage(msg));

```
But when I add a __additional parameter__ to my "handleEntityValueMessage" method and thus to the Lambda Expression I get an exception

```
Messenger.Default.Register<ResolveEntityValueMessage>(this, (msg)=>handleEntityValueMessage(msg,servicelocator));

```

When removing the parameter again from the handleEntityValueMessage method and from the lambda no exception is thrown.

I don't know if this issue is related to : http://mvvmlight.codeplex.com/workitem/7579 pls check it.
I can reproduce it in the current release .
