Ah, now I see what's the problem. As I've already explained, the code is not 
correctly generated since the string is passed as a reference and modified in 
C++. In C# this has to be an 'out' parameter. I'll look into this in the next 
week.
To work round this you can simply use QIODevice.ReadLine(). It doesn't use a 
buffer and simply reads till the end of the line. This works fine on my 
setup:
        [Q_SLOT]
        public void DataReadyOnStdin() {
            Console.WriteLine(this.stdin.ReadLine().ConstData());
        }

Oh, actually I'm on Gentoo ~amd64, too. There's qt-4.4.0_rc1 in portage and 
that works quite well. :)
