Sod will_paginate library

I'm using Rails 2.1 and and will_paginate 2.3.2. I have the following models:

class Product < ActiveRecord::Base

has_many :product_audience_associations

has_many :audiences, :class_name => "ProductAudience", :through => :product_audience_associations

end

class ProductAudience < ActiveRecord::Base

has_many :product_audience_associations

has_many :products, :through => :product_audience_associations

end

class ProductAudienceAssociation < ActiveRecord::Base

belongs_to :product

belongs_to :audience, :class_name => "ProductAudience", :foreign_key => :product_audience_id

end

When I go to save a product record, I get the following error trace with the error message "stack level too deep":

If I remove will_paginate, things work out... but, then I don't get to paginate with will_paginate, which makes me sad.
