Output of Xorg -configure run in the vm

((INTRO
I'm getting a segfault with a mysterious stacktrace (OsLookupColor being on top) if I try to get a sample configuration file form my system. The command that causes this is:

$ Xorg :0 -configure
or
$ Xorg -configure

((HARDWARE
I tried this inside of two different hardware environments.

1) Lenovo T410 (64Bit) 
2) A one month old Virtuabox VM downloaded from http://www.osboxes.org/arch-linux/ (32Bit)

On both machines I installed the usual arch linux packages xorg-server, xorg-server-utils, xorg-utils and in the VM i aditionally installed virtualbox-guest-utils in order to get the graphics driver.

On both systems I made sure that I was able to start a normal (minimal) X session using startx and twm.
