No more GNOME after updating to KDE 3.4 in KDM

Hello List, I got a little Prob with KDM after Updating to 3.4. KDM is not giving me the option to start GNOME anymore. I got GNOME 2.8 from ULB installed, but it is not shown up in the PopUp Selection. If I use GDM both are shown up, KDE and GNOME (and others) like before, and i can login to both. Any Idee what i could modify to get back Gnome in KDM ? Thanks Micha
