Do you mean:
  YAML::load(File.read('file'))

What do you get when you call to_yaml on your struct ('ss' is a struct 
instance):
  irb(main):013:0> ss.to_yaml
  => "--- !ruby/struct:Customer \nname: foo\naddress: addr\n"
  irb(main):014:0> YAML.load(ss.to_yaml)
  => #<struct Struct::Customer name="foo", address="addr">

Hash of structs works similarly.
Are you checking the file before you read it back in?

Daniel
