Problema no Gnome Compiz Preferences

[Igo]

Olá amigos, estou usando o Ubuntu 7.04, com o Gnome Compiz Preferences...
Fui abrir o programa pelo terminal e percebi alguns erros:

igo@igo-desktop:~$ gnome-compiz-preferences

** (gnome-compiz-preferences:5630): WARNING **: plugin crashhandler isn't installed

(gnome-compiz-preferences:5630): libgnomevfs-CRITICAL **: gnome_vfs_get_uri_from_local_path: assertion `g_path_is_absolute (local_full_path)' failed

** (gnome-compiz-preferences:5630): WARNING **: plugin showdesktop isn't installed

** (gnome-compiz-preferences:5630): WARNING **: plugin inputzoom isn't installed

** (gnome-compiz-preferences:5630): WARNING **: plugin animation isn't installed

Alguém poderia me ajudar? Agradeço!
