Problem with plone.app.contenttypes and plone.app.multilingual

Hi,

I'm not sure if this is a bug or if I'm not understanding how to use plone.app.multilingual. The next buildout reproduces the issue:

[buildout]
extends = http://dist.plone.org/release/4.3.6/versions.cfg
parts = instance

[instance]
recipe = plone.recipe.zope2instance
user = admin:admin
http-address = 8080
eggs =
    Plone
    Pillow
    plone.app.contenttypes
    plone.app.multilingual

[versions]
setuptools = 6.1
zc.buildout = 2.2.5
zc.recipe.egg = 2.0.1
plone.app.contenttypes = 1.1b5
plone.app.event = <= 1.1.999
plone.app.multilingual = 2.0.0

I setup the zope instance and then I created a new Plone site activating plone.app.contenttypes, and plone.app.multilingual. However, after creating the site I was redirected to http://localhost:8080/Plone/en, that does not exists yet and raises an "This page does not seems to exists". If I go to http://localhost:8080/Plone/front-page the page looks fine, but if I go to http://localhost:8080/Plone the site redirects me to http://localhost:8080/Plone/en.

Then I created a second site but I also include dexterity content types as a requirement when creating the site. In this second site the previous issue does not occur. However, not language folders where created. Thus, added Espa├▒ol to the languages of the site. It creates the folders /en and /es. I added a page inside /en. Inside the created document I click "Translate to Spanish". Then, I got the error "This page does not seems to exists".

Is this an issue or I'm not using translations correctly?
