Evolution breaks my desktop

Hi, When I am running the Evolution that is included with 8.1, and I select 'Configuration of Evolution', it breaks down with a multitude of dialog boxes with different error messages, and sends me into Nautilus. After that Gnome has conquered my desktop, and all my KDE icons and wallpaper is gone. I then must kill all Gnome processes and reload KDE to get things going again. Someone seen this before?
