Conflicting types for parameter containers.

With a "complex" form, i have the error below

My form look like this :

file index.html.erb

<% remote_form_for ...  do |f| %>
<%= f.text_field :first_name %>
<%= render :partial=>"/addresses/item" %>
<% end %>

File item.html.erb

<%= text_field_tag "address[street]",address.street %>

With Rails 2.2.2, no problem with Rails 2.3.0, I have this error :

  Status: 500 Internal Server Error
  Conflicting types for parameter containers. Expected an instance of Hash but found an instance of String. This can be caused by colliding Array and Hash parameters like qs[]=value&qs[key]=value. (The parameters received were "".)
