Network Manager 0.7 fails connecting to PPTP

[kaman]

Binary package hint: network-manager-pptp

Network Manager reports "The VPN connection 'corbina' failed because the VPN service failed to start." when I try to connect to my ISP's PPTP server. Manual connection with pppd & pptp to this server runs successfully.
