I installed the latest 6.1 Version on Ubuntu 12.04. Only testing the demo data's i get above client error when using the web client. In this case when trying to view a quotation order.

This happens when installing den .deb version as well as following the www.theopensourcerer.com/2012/02/how-to-install-openerp-6-1-on-ubuntu-10-04-lts steps.

No print - no use :(

Does anybody have the same problem or does anybody have a solution?
