Chris, I'm not seeing this crash on Gnome with compiz enabled. In fact, if I login to a gnome session (with compiz enabled, but that doesn't matter for this example), and then choose to switch users, and login another user to a KDE session, I don't see this crash. In a case like that, however, kwin's compositing is naturally disabled, and that's, I presume, the reason I can complete a flawless login.
About the backtrace, if I find the time, I will definitely try to capture it for you.
