Vagrant VM Provider Config + SSH Forwarding = Error?

Relative Vagrant and Ruby newb here. I'm trying to enable SSH forwarding from my Windows machine to my Vagrant created Ubuntu VM. My Vagrantfile has some provider specific config:

config.vm.provider "virtualbox" do |v|

v.name = guestHostname

v.memory = 8192

v.cpus = 2

v.customize ["modifyvm", :id, "--vram", "128"]

v.gui = true

end

Works fine and dandy by itself. But when I add the config for SSH forwarding:

config.ssh.forward_agent = true

Running 'vagrant up' starts failing with this error message:

Commenting out the provider specific config makes the error go away. Any ideas on what could be causing the issue?

(thanks in advance for the help!)

It turned out that I just needed to upgrade Vagrant - there was a known bug in the version that I was using (although I'm still not clear why adding the SSH forwarding config was triggering the issue).
