kdvi-Problem

Hi, today I have installed the brand new KDE2. The new kdvi - viewer seems to not understand the "-paper" option, which is send by lyx to the viewer-app. Kdvi fails to show the dvi-preview. Has somebody an idea, how to get lyx to work with the kde2-dvi-viewer ? Thanks for help, Torsten.
