Vagrant error message missing line numbers on Windows 7

[eis]

Example Vagrantfile:

# -*- mode: ruby -*-
# vi: set ft=ruby :

foo

And output:

C:\Users\myuser\repos\test>vagrant up
There was an error loading a Vagrantfile. The file being loaded
and the error message are shown below. This is usually caused by
a syntax error.

Path: C:/Users/myuser/repos/test/Vagrantfile
Line number: /Users/myuser/repos/test/Vagrantfile
Message: NameError: undefined local variable or method `foo' for main:Object

Expected: line number printed together with error message
Actual: path to vagrant file printed where line number should have been printed

Using Vagrant version 1.7.4.

By comparison, on Mac OS X line number is printed just fine:

$ vagrant up
There was an error loading a Vagrantfile. The file being loaded

Path: /Users/myuser/repos/vagrant-test/Vagrantfile
Line number: 4
