This is not the proper way of getting the newly created pages. The reasons are:
* slugs are not unique => above 'get' can raise MultipleObjectsReturned
* even for the same page, if CMS_LANGUAGES has more than one language, multiple title objects are created for each page
* if CMS_MODERATION = True the same page will have two versions: draft and published, both having their own title_set, each having at least one title object, both having the same slug.

I would rather do it like:

    new_page = Page.objects.order_by('-id')[0]

This would work because:
* didn't expliclty provide the id 
* since id is auto_increment
* page_data['published'] = False (a single page object is created)
=> the newly added page has the biggest pk
