28070	set_language (i18n) without next does not change language if called from a language prefixed URL	Monsieur Cellophane	nobody	"Greetings. 

**Preamble**:
Switching language by posting to set_language with an empty next parameter causes a redirection to the REFERER url, as per the documentation.

**Description**:

What this means is that if language selection is made from a language-neutral URL (say /about/), selecting english as language the redirection in set_language will land the user to /en/about.

If - however - a new language selection (say de) is now made from /en/about/, the landing spot will be (again) /en/about, rather than the expected **/de/about**. The new language (de) is now, however, memorised in the user's session.

**What should happen:**
Invoking set_language from a language prefixed page with an empty ''next'' parameter should redirect to the language-neutral URL, allowing the session based url selection to kick in.

**What would help:**

Of course, being able to reference the current language-neutral url as the ''next'' parameter to set_language would achieve the result. However,  language-neutral urls aren't availble in templates (or anywhere I looked); so one's best hope is writing a custom template filter that strips the language prefix from a URL and hen use the stripped request.path (or request.get_fulL_path) as the ''next'' parameter to the POST."
