I think this is actually slightly different from the bug upstream, and is a GDM problem (but unless we can repeat it is essentially unfixable).

I think it is very different from the bug upstream, since it is related to a Xnest issue.

Install xnest, and run this : gdmflexiserver --xnest

It should close quickly after launching, exactly in the same way when choosing a nested session from the fast-user-switch-applet.
