ActiveResource breaks when encounters <object> tag in XML

I'm not sure if this is a bug, or is it me misusing #to_xml, but I get "Wrong number of arguments" when trying to load a model which has <object> tag in its xml representation.

The reason seems to lie in find_or_create_resource_for(name) in ActiveResource::Base. I traced the issue down to the following point.

Let's say our model is Post. Here's what's going to happen:

      def find_or_create_resource_for(name)
        # name is "object"

        resource_name = name.to_s.camelize
        # resouce_name is "Object"
        
        ancestors = self.class.name.split("::")
        # ancestors is ["Post"]

        if ancestors.size > 1
          find_resource_in_modules(resource_name, ancestors)
        else
          
          self.class.const_get(resource_name)
          # ===> This line will return Object, not Post::Object,
          #      which breaks because ActiveResource calls Object.new(value)
          #      but Object's initializer doesn't take args.
        
        end
      rescue NameError
        if self.class.const_defined?(resource_name)
          resource = self.class.const_get(resource_name)
        else
          resource = self.class.const_set(resource_name, Class.new(ActiveResource::Base))
        end
        resource.prefix = self.class.prefix
        resource.site   = self.class.site
        resource
      end

As mentioned above - the const_get returns Object, and then ActiveResource tries to call Object.new(value), whereas Object constructor doesn't take params.

This causes "Wrong number of arguments (1 for 0)" error when attempting to do Post.find(:last) on the ActiveResource client.

One way to fix it is to raise NameError explicitly.

      def find_or_create_resource_for(name)
        resource_name = name.to_s.camelize
        
        # ==> Adding this line fixes the error. 
        raise NameError if resource_name == "Object"
        
        ancestors = self.class.name.split("::")
        if ancestors.size > 1
          find_resource_in_modules(resource_name, ancestors)
        else
          self.class.const_get(resource_name)
        end
      rescue NameError
        if self.class.const_defined?(resource_name)
          resource = self.class.const_get(resource_name)
        else
          resource = self.class.const_set(resource_name, Class.new(ActiveResource::Base))
        end
        resource.prefix = self.class.prefix
        resource.site   = self.class.site
        resource
      end

Raising NameError causes execution to jump to the rescue clause where "object" is handled properly. Should this be fixed?
