Did some more testing : it only happens on the first login after boot. On subsequent login, gnome-settings don't crash and dual monitor configuration is ok.

When moving from one monitor to the other, the monitor doesn't get a signal. Opening the display manager shows the screen blackened, and trying to enable it brings about the following error: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.SettingsDaemon.XRANDR_2' on object at path /org/gnome/SettingsDaemon/XRANDR restarting X11 solves this, but of course means I have to exit any open window, and reconfigure my dual monitor layout each time. this was 100% fine in 11.10. this happens when moving from either screen to the other.
