Good day. I installed Odoo version 10.0-20161028 (Community Edition) on Antergos Linux.I create a new Customer in the Sales App as a company, then I try to create a Contact. I click on the save button after creating the Contact and the following error is displayed. What can be the cause of this error? It looks like all breaks down after calling a function to manage an image, however I updated nothing but the text fields related to the contact.
