I have just come from Ubuntu and I have the "no padlock" issue when connected to a VPN. I do get the spinning disc while it is connecting however.
I use PPTP VPN a lot to access servers and occasionally I lose the VPN connection. With Ubuntu I got a notification of this and the padlock disappeared. Linux Mint gives no notification of connected or lost connection.
