[David Francos Cuartero (xayon)]

Had the same issue, turns out that oemedical_lab_view extends oemedical_menu... but oemedical_menu is loaded AFTER oemedical_lab_view, so it does not exist yet.

You need to fix addons/oemedical/__openerp__.py

Put 'oemedical_menu.xml' in data section just before oemedical_lab_view.xml

I've attached a patch that fixes it.
