Can't get past "General Configuration"

Continuum r511964 has a problem, you can't get out of General Configuration. All the integration tests are failing.

From a fresh install, here's what happens:
1. Create Admin user
2. General Configuration
3. Save
4. Login screen
5. Login as admin
6. General Configuration
7. Any other link -> General Configuration

It used to be:
1. Create Admin user
2. Login screen
3. Log in as admin
4. General Configuration
5. proceed as usual
