Same shit. An archlinux user but i have the same errors with gvim and no errors with 'gvim &'. I'm using x86_64 multi-core system now (i have i686 one-cored celeron and things are fine there). I do not use xmonad - notion instead, so it definitely not related to wm. Software versions: kernel: 3.0.4-1 gvim: 7.3.322-1 xorg-server: 1.10.4-1
