Hi,

The "connect to server" dialog lists all protocols it supports, even if gnome-vfs doesn't support this particular protocol:
... (./src/nautilus-connect-server-dialog.c:)
        gtk_combo_box_append_text (GTK_COMBO_BOX (combo),
                                   _("SSH"));
        gtk_combo_box_append_text (GTK_COMBO_BOX (combo),
                                   _("Public FTP"));
        gtk_combo_box_append_text (GTK_COMBO_BOX (combo),
                                   _("FTP (with login)"));
        gtk_combo_box_append_text (GTK_COMBO_BOX (combo),
                                   _("Windows share"));

For example it's possible to create a link to a Windows share on the desktop, even if gnome-vfs doesn't support smb.  This is not very good from an integration perspective, it would be nicer to filter out unsupported protocols.

This is Debian bug http://bugs.debian.org/354984.

Cheers,
