Just installed LibreOffice 4 on my Xubuntu 12.04 System. It doesn't work. I get the splash screen and then -- nothing. Running it in Terminal I get the following errors:

(soffice:14860): Gtk-WARNING **: Unable to locate theme engine in module_path: "equinox",

(soffice:14860): Gtk-WARNING **: Unable to locate theme engine in module_path: "equinox",

WARNING: gnome-keyring:: couldn't connect to: /tmp/keyring-40Nvt0/pkcs11: No such file or directory
Any ideas?
