The second call works because adding [] to the proxy object produces a new true Array object.

The common use case for this would be if you were trying to serialize something like this code
class User < ActiveRecord::Base
has_many :pets
end
class Pet < ActiveRecord::Base
belongs_to :user
end
user = User.first
RocketAMF.serialize(user.pets, 3)
I trounced around in the C code a bit, but it's not immediately obvious to me what the problem is, as I don't have a lot of experience in native ruby C api. If I have some time I will put together a spec for this.
