Geis crashes when it fails to connect to XCB gesture service

Hi everybody, I am trying to use utouch and touchegg on Arch Linux. I've compiled the following packages from bzr master as of today:

local/utouch-evemu-bzr 41-1 (unity2d-bzr)
    Event Emulation for the uTouch Stack
local/utouch-frame-bzr 41-1 (unity2d-bzr)
    Touch Frame Library
local/utouch-geis-bzr 156-1 (unity2d-bzr)
    Implementation of the GEIS (Gesture Engine Interface and Support) interface.
local/utouch-grail-bzr 166-1 (unity2d-bzr)
    Gesture Recognition And Instantiation Library

When I run geistest I get:

alessandro at alessandro-thinky in utouch-geis-bzr
$ geistest $(xwininfo -root | grep "Window id" | awk '{print $4}')
*** glibc detected *** geistest: free(): invalid pointer: 0x0000000001d79b58 ***
