Dear all,

Today, after a fresh install of Odoo v9, I get the attached error when trying to create a new database. The error is:

Database creation error: "Mixing apples and oranges: None in res.groups(5, 4)" while parsing /opt/odoo/openerp/addons/base/security/base_security.xml:18, near

<record model="res.groups" id="group_system">
    <field name="name">Settings</field> 
    <field name="implied_ids" eval="[(4, ref('group_erp_manager'))]"/> 
    <field name="users" eval="[(4, ref('base.user_root'))]"/> 
</record>

I have confirmed everything and my odoo-server.conf is: 

admin_passwd = admin
db_host = False
db_port = False
db_user = odoo
db_password = admin
addons_path = /opt/odoo/addons

User odoo is already created on postgresql and the password set is "admin".

This is not the first time I install odoo 9 using the method used, and never had problem like this.

What could be the reason?

Regards

Paulo
