Comment 4 for bug 153294

No, this is actually not fixed in Hardy with all the updates.

I installed package network-manager-openvpn and the element "VPN connection manager (vpnc)" appeared as unselected.

I went to "Edit Menus", made this element to be shown and after clicking on it:
Error: could not find «nm-vpn-properties» (No such file or directory)

Looking at the properties I see the following command:
nm-vpn-properties --import-service org.freedesktop.NetworkManager.vpnc --import-file %f

But nm-vpn-properties is not on the PATH, and that is why it is not found:
roger@roger-laptop:~$ nm-vpn-properties
bash: nm-vpn-properties: command not found

However the nm-vpn-properties program it is installed under:
/usr/lib/network-manager/nm-vpn-properties

which is not in PATH
echo $PATH
roger@sindreu-laptop:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

So I suppose you should include nm-vpn-properties to a different directory or simply specify the whole path in the gnome menu.

Let me know if you need anything else.

Thanks.
