Comment 2 for bug 776503

While looking a bit further: xfce4 -> (depends) -> thunar -> (recommend) -> gamin (only)

Package: thunar
Section: xfce
Architecture: any
Depends: ${shlibs:Depends}, ${misc:Depends}, desktop-file-utils,
 shared-mime-info, thunar-data (= ${source:Version}), exo-utils
Recommends: hal, dbus-x11, gamin, ${shlibs:Recommends}, thunar-volman,
 xdg-user-dirs

If thunar would state gamin | fam that might solve the problem where I get:

root@localhost:~/XFCE# apt-get install xfce4
