Was there an existing Italian translation? If not, it's Special:myLanguage doing its thing. This is a temporary situation, to help translators do a quick job of reorganising the page. Cut and paste from the old translation, instead of having to carefully translate. There is only Danish and Ukrainian to be done, after which the old stuff can be deleted from all the pages. I'd expect that to be done within the next few days. Hope that makes sense to you. The reorganisation is big, so we were trying to help cut down work.
Hi, thanks for the answer. It affects all the translated pages. The reorganization is now completed as you can see here http://userbase.kde.org/index.php?title=Digikam%2FTutorials&action=historysubmit&diff=172679&oldid=170002
