problem with kpersonalizer and spanish

Hello Using Kubuntu 10.04 and trinity 3.5.13.2 I encountered the following problem. If I change the language environment from English to Spanish via kpersonalizer, - the icons become smaller - some applications such firefox crash with a signal 11 type error and a reference to gtk-qt-trinity. However kgtk-qt3-trinity is not installed. After removing the .trinity directory and restart trinity, but sticking to English everything is ok Has anybody found similar problems? Thanks Uwe Brauer
