Switching database in login screen gives Internal server error

on 5/6/15, 8:07 AM 1,576 views

Impacted versions:

8.0 at least

Steps to reproduce:

Open a runbot

Before login change database to uuid-whatsoever-base

Change back database to uuid-whatsoever-all

Current behavior:

HTTP 500 Internal server error

Reloading the page fixes the problem

Seems to happen only on the login page when website module is not installed

Logs give

Flawless switch between databases
