I investigated.

The file-set signal was added in GTK+ 2.14:
http://library.gnome.org/devel/gtk/unstable/GtkFileChooserButton.html#GtkFileChooserButton-file-set

It was not wrapped in gtkmm 2.14 because it is a G_ACTION_SIGNAL, which
are usually not public API. But looking at the bug that added it, I
think that it is meant to be used by applications:
http://bugzilla.gnome.org/show_bug.cgi?id=353196

I have added it in svn trunk so it will be in gtkmm 2.16. In the
meantime you may it via the C API with gobj().
