Why can't active resource deserialize this xml response?

Can anybody explain why active resource can't deserialize this?

Active Resource class:

class Pownce < ActiveResource::Base     self.site = "http://api.pownce.com/1.0&quot; end

class User < Pownce end

Command I'm using:

User.find(:all, :from => '/users/eggie5/friends.xml')

Resolves to this:

GET http://api.pownce.com:80/users/eggie5/friends.xml --> 200 OK (<?xml version="1.0" encoding="utf-8"?> <users>     <user>         <username>casseeee</username>         <permalink>http://pownce.com/casseeee/&lt;/permalink&gt;         <short_name>cassee a.</short_name>         <country>United States</country>         <age>20</age>         <first_name>cassee</first_name>         <blurb></blurb>         <gender>Lady</gender>         <profile_photo_urls>             <smedium_photo_url>http://pownce.com/profile_photos/c/a/s/ casseeee/31250_smedium.jpg</smedium_photo_url>             <small_photo_url>http://pownce.com/profile_photos/c/a/s/ casseeee/31250_small.jpg</small_photo_url>             <tiny_photo_url>http://pownce.com/profile_photos/c/a/s/ casseeee/31250_tiny.jpg</tiny_photo_url>             <medium_photo_url>http://pownce.com/profile_photos/c/a/s/ casseeee/31250_medium.jpg</medium_photo_url>             <large_photo_url>http://pownce.com/profile_photos/c/a/s/ casseeee/31250_large.jpg</large_photo_url>         </profile_photo_urls>         <is_pro>0</is_pro>         <location></location>     </user>     <user>         <username>elagothro</username>         <permalink>http://pownce.com/elagothro/&lt;/permalink&gt;         <short_name>Michael O.</short_name>         <country>United States</country>         <age>22</age>         <first_name>Michael</first_name>         <blurb>PHP/MySQL Dev Lead for foliopod ( http://chicagofolio.com &amp; http://foliopod.com ) and CareerNoodle ( http://careernoodle.com )</blurb>         <gender>Dude</gender>         <profile_photo_urls>             <smedium_photo_url>http://pownce.com/profile_photos/e/l/a/ elagothro/96840_smedium.jpg</smedium_photo_url>             <small_photo_url>http://pownce.com/profile_photos/e/l/a/ elagothro/96840_small.jpg</small_photo_url>             <tiny_photo_url>http://pownce.com/profile_photos/e/l/a/ elagothro/96840_tiny.jpg</tiny_photo_url>             <medium_photo_url>http://pownce.com/profile_photos/e/l/a/ elagothro/96840_medium.jpg</medium_photo_url>             <large_photo_url>http://pownce.com/profile_photos/e/l/a/ elagothro/96840_large.jpg</large_photo_url>         </profile_photo_urls>         <is_pro>1</is_pro>         <location>Chicago, IL</location>     </user> </users>

It's simply a collection of 2 User objects. Can somebody enlighten me as to why this won't deserialize? This is the error:

NoMethodError: undefined method `collect!' for #<Hash:0x12a86bc>   from /usr/local/lib/ruby/gems/1.8/gems/activeresource-2.0.2/lib/ active_resource/base.rb:465:in `instantiate_collection'   from /usr/local/lib/ruby/gems/1.8/gems/activeresource-2.0.2/lib/ active_resource/base.rb:439:in `find_every'   from /usr/local/lib/ruby/gems/1.8/gems/activeresource-2.0.2/lib/ active_resource/base.rb:385:in `find'

Doesn't this effectively exclude any non-rails webservice from being used with active resource?

Is this just acceptable to you?

This isn't a rails webservice, so I can't make those edits. This isn't a standard of rest or anything...
