The crash is because XGetWindowAttributes is throwing a BadMatch error, which is unexpected. It will throw a BadMatch error (from dixLookupWindow) if the specified window isn't really a window. This might happen if a window is destroyed and replaced with a drawable of the same ID whilst gnome-settings-daemon is handling the original CreateNotify event.
This looks like it's basically the same issue as https://bugs.freedesktop.org/show_bug.cgi?id=23562, except with XGetWindowAttributes instead of XGetWindowProperty. Perhaps XGetWindowAttributes needs a similar fix?
