This isn't correct, of course. It just happens to do something kind of useful when the deferred generator is a trial test method. In other cases, it would be weird to find the __doc__ of the returned object to be the __name__ of the wrapped function.
In Python 2.4, setting __name__ works, and deferredGenerator tries to do that, so trial will only have this problem with Python 2.3. You could define a helper function for your tests which calls deferredGenerator and sets __doc__ appropriately, if switching to Python 2.4 isn't an option.
