cannot connect pptp-vpn after upgrading via apt from 1.0.* to 1.1.93

[Wei Tsui]

After upgrading, the connection of VPN failed immediately I select the "VPN1" connect option in nm-applet.

I remove the VPN1 and re-create again, but still failed to connect.

when running "nmcli c up VPN1", it replies failing of "unknown reason".

==============

I roll back the version to 1.0 and then it works well!

Currently I am using rolled-back version of network-manager-pptp,

so don't care much about the appending logs.

The issue of VPN connection bug comes from the version: 1.1.93.

After ungrading network-manager to 1.1.93, though I failed to connect VPN though nm-applet,

however, If I use "pptpsetup .. ; pon .. ; ip route add default .." to establish PPTP VPN, then VPN will be able to connect successfully.

So I think it's definitely the bug from network-manager instead of linux drivers or my network environment.

Fixed after upgrading network-manager-pptp*
