The error with the builder file is simple to fix. This line needs to be removed from https://github.com/mate-desktop/mate-screensaver/blob/master/data/mate-screensaver-preferences.ui#L38

Now

Removing this line
https://github.com/mate-desktop/mate-screensaver/blob/master/data/mate-screensaver-preferences.ui#L297
starts the window.
