I have checked your problem, and I could reproduce the said error which you've mentioned when installing POS with demo data.
Actually the problem is you are using stable 6.0 (server and addons) and if I am not mistaken you have only replaced the point_of_sale module which is not correct. If you want to use the latest trunk version of point_of_sale then you must use all the trunk series for server, client and addons. It will solve your problem.
Can you please check with latest code and let us know?
