Subject: [PATCH] Ignore exceptions when a resource can not be found

We silently ignore exceptions when a resource can not be found.
This may happen, when a language switcher is mounted on a 404 page but that one is not routable.
We now return an empty URL in this case instead of bailing with an HTTP 500.
