That's not what I get.  I see:

  TypeError: unbound method _q_index() must be called with Klass
  instance as first argument (got HTTPRequest instance instead)

Putting a class in _q_exports doesn't work because Quixote does not
instantiate it.  You could do something like this:

    from myClassPythonfile import myClass

    _q_exports= ["myPage"]

    def myPage(request):
        return myClass()

If you don't want to create one instance per request you could do
this:

    from myClassPythonfile import myClass

    _q_exports= ["myInstance"]

    myInstance = myClass()

HTH,
