Re: UTF8 exception in Nunit 2.4.8

In the very last lie of your stack trace, we can see that
NUnit is in the constructor of it's ContextHolder class.

The ContextHolder is trying to save the value of Console.Out
so it can be restored later. An exception is being thrown,
within the .NET code. 

Have any of your tests run before this point? That would
seem to be the only way that the value of Console.Out
could get messed up.

Also, what's your environment?
