Onboard won't launch - segfault

Hey. I'm trying to launch onboard for a device that (will) have no keyboard. I'm using the latest developmental xserver which I think may be associated. Obviously dev versions probably won't play well with other dev versions. In any case please tell me if I did something stupid wrong.

Here's the seg dump

xserver versions for reference...
