Hi everybody. I tried to solve this problem myself but I had no luck

After upgrading KDE from 4.1.3 to 4.3.0 system shows some menues in English and some in Spanish. Dolphin is in English, Kmenu tabs (Favourites, Applications, etc) too but Kmenu items are in spanish.

I tried to download language packages with Yast but was a no go. Any hint?
