I'm using Archlinux and suffer for this same bug. I get to, sort of fixed, after I realize the way that gnome screen settings was working. using gnome 3 and plug-in a second monitor it extend. But when I want to use only the external screen it crash the way it's described here. I try many ways to change but it always crash until I realize the representation of the screens in the gnome-settings dialog. It seems that one screen is overlapping the other (only happen when one is turn off), not at the right of it, is like in the middle. I think it was just a bug but after many times i realize that the crashed graphics was cut in the middle. It seem that the screen signal is splited into the two screens and crashed. To fixed, I just grab the screen i want to use to far away from the other (not next to it) and voila! X don't crash. I don't know this could be useful but for me fixed. I hope I made myself clear.
