Update 3.3.x i18n_base issue

[Rene]

I've tried it several times but renaming a page slug results in Page Not Found!

Example:
- Create new page 'Feedback' & save page ( slug = feedback )
- Calling page (click menu item) is working ok (tested)
- Edit Page and rename slug to 'beoordeling' & save page
- Calling page (click menu item) results in 404 ( see http://test.dare-is.nl/beoordeling/ )

File: beoordeling.xml

Code:
