RESTful WS module doesn't work with internationalised nodes

I have a multi-lingual Drupal site, where nodes are translated into several languages using Locale module and Content Translation.
RESTful WS doesn't seems to work with nodes that has a translation, but it work well with nodes that are only in one language.

Let's say that node #1 is an article in English. Let's say that node #3 is another article in English with node #4 is the trnaslation of #3 to French.

The query curl -v http://localhost/?node/1.json gives me the JSON content of the node #1
The query curl -v http://localhost/?node/3.json gives me a redirection (HTTP 301) to curl -v http://localhost/?node/3

It's a big problem for me, as I really need a CMS who is both multi-lingual and RESTful...

Thanks in advance !
