I was about to file a very similar bug. I made a quick mockup showing a couple improvements:
-The window title and text are more informative, now you see exactly what happened.
-The message itself is bold, to stand out.
-There is only one button, close. Having two buttons that did the same thing only confused the user.
I think that should be more than enough. A simple dialogue on your desktop when you come back. Anything beyond that would be over the top, in my opinion.
