There is a newline error in one of the unit tests, present on Windows.

The error is here, in the code of the text report writer:

if(exception != null)
  writer.WriteLine("FAILED with an exception:\n{0}", exception);
else
  writer.WriteLine("FAILED");

There is an explicit \n in there. Instead it should use Environment.NewLine.
