Auto connect my PPTP VPN client when login

Hi

I have installed the Ubuntu 13.04 Desktop version on my PC and everything was working fine till the moment I have configured a PPTP VPN session attached to my Ethernet Wired Connection. The pb I have is that as soon as I have ticked the option "Automatically connect to VPN when using this connection" on my Wired Connection 1, the Ethernet is not activated automatically anymore by the login script and I have to do it manually. It works fine manually but I'd like to have it done automatically.

Any idea how can I fix this issue?

Thanks.
