network-manager-gnome missing dependency on libnm-glib-vpn1

network-manager-gnome is missing a dependency on libnm-glib-vpn1, without which nm-applet fails to start up.

$ nm-applet
nm-applet: error while loading shared libraries: libnm-glib-vpn.so.1: cannot open shared object file: No such file or directory
$ ldd /usr/bin/nm-applet | grep 'not found'
 libnm-glib-vpn.so.1 => not found

The package also FTBFS because it’s missing a build dependency on libnm-glib-vpn-dev.
