i pry'd into:

def output_and_errors_from_command(cmd) #:nodoc:
unless defined? Open3
begin
require 'open3'
require 'win32/open3'
rescue LoadError
end
end
begin
require 'pry'
binding.pry
out, err, status = Open3.capture3(*cmd, :binmode => true)
[out, err, status.exitstatus]
rescue NotImplementedError, NoMethodError
IO.popen( *cmd ) do |stdout|
stdout.binmode
[stdout.read, nil, nil]
end
end
end

and found the command being constructed ran without errors when i ran it in my console directly
