It looks like the code producing this error isn't the code you've posted
above. Anyway, the interface is defined as:

public interface Preferences : GLib.Object {
        public static GLib.Quark error_quark ();
        public abstract void merge (Anjuta.Preferences prefs) throws GLib.Error;
        public abstract void unmerge (Anjuta.Preferences prefs) throws GLib.Error;
}

so the methods should be implemented as
public void merge (Anjuta.Preferences prefs) throws GLib.Error {
        //...
}
public void unmerge (Anjuta.Preferences prefs) throws GLib.Error {
        //...
}

Is that what you're doing?
