Opensuse 12.1 and small fonts in evolution menues

After a fresh installation of OpenSuse 12.1 and the Import of the saved evolution data, everything is fine and works properly, but every menu in evolution is very fine and small, maybe 8 points. What can I do, to have a bigger menu font? The evolution release is 3.2.1
I use KDE, not Gnome, in Gnome the menus have a bigger font and are better readable for me.
