[trunk] pop from empty list

[Pollet Alexandre]

On a new database:
I have created a new company (company 2) with parent_id = "Your company"
I have created a new user with company_id=company2 and company_ids=[company2]

Install sale and purchase module (setup configurations).

When I'm logged with the new user and I click on product menu I have this error:
