[arch-general] Gnome crashing with segmentation fault - Not sure about the source

Dear all, Gnome is crashing on my machine[1] with the typical "Oh no, something has gone wrong" message. XFCE starts and works fine, though. The gnome crash leaves this message[2], but from it is not clear to me which is the root of the problem. Setting the backlight, or something wrongwith the intel drivers? Any insight about it is appreciated. [1] http://www.thinkwiki.org/wiki/Category:X200_Tablet [2] https://dl.dropboxusercontent.com/u/1390205/Xorg.0.log
