Thanks for your answers. I use the following base view for all my views
and it works perfectly:

class BaseView(grok.View):
    """."""
    grok.baseclass()

    def namespace(self):
        return {'target_language': self.request.locale.getLocaleID()}

getLocaleID() returns the same result as:

    from zope.publisher.browser import BrowserLanguages
    lang =
unicode(BrowserLanguages(self.request).getPreferredLanguages()[0])
