Thunar didn't integrate cleanly with the GNOME session. Drop the
XFCE file-manager module (thunar/xfconf/exo/tumbler) and restore
Nautilus as the native file manager: un-exclude nautilus, point the
dash favorite at org.gnome.Nautilus.desktop, remove the Thunar
desktop override, and keep gvfs (moved into gnome.nix) for mounting,
trash, and network shares. Add file-roller for archive-manager
integration in Nautilus.
