Whilst logged in as admin and attempting to select a user from the treeview I intermittently get an error. When it happens, selecting the form view whilst in the treeview and then selecting "Next" until I get to the correct record seems to work. Any ideas?

Odoo Client Error
TypeError: this.fields is undefined
