I have the same issue. 

I was implementing a kind of filter for the user authentification on the Request Factory. I have subclassed my RequestFactoryServlet and I just check if the user is authentificate, if not I send a Redirection to the login page. So I think that my call from the client side is waiting for a particular response from the server, but the client never get it because I make a redirection and I don't call "super.doPost()" in the servlet.

But I don't understand why the RequestFactrory workflow don't fire the failure function on client side?

I don't think that a good way to make my login workflow any way. I will try to find authentification examples with Google Accounts with GWT/GAE.

Here is the stacktrace maybe it can help you :)
