Since the update to Gtk+-3.14 the margins of some dialogs are too small. That indication-error is caused by the "Object (use_header_bar: 1);"-workaround to hide the close-buttons.
To fix that remove theese lines:
Object (use_header_bar: 1); (this.get_header_bar () as Gtk.HeaderBar).show_close_button = false; this.get_header_bar ().get_style_context ().remove_class ("header-bar");
And replace it with: this.deleteable = false;
