I rebuilt network-manager-openvpn including your patch, and tried it: Still no passphrase dialog. Knetworkmanager shows a scrollbar, but this gets stuck at 80%. After a few seconds there is a bubble saying
VPN Connect Failure
Could not start the VPN connection 'myvpn' due to a connection error.
The VPN login failed because the VPN program could not connect to the VPN server.
/var/log/daemon.log says
ERROR: could not read Private Key username/password/ok/string from management interface.

Seems that the patch doesn't help :-(
