Hi Javier. For the last couple of days we've been fighting to find out why we couldn't translate the KDE_preinstalled page. Did you, by any chance, simply create the page and type in the translation, rather than using the Translatewiki system? It appears that the problem began about the time you made this page. To test the theory I'm going to delete that page. If it lets me, I'll know that it wasn't created within the system.
