title: Using Friendly ID and i18n with update_attributes causes overwrite
body: <p><strong>Using:</strong>
  - Rails 3.0.3
  - Friendly_id 4.0.0 Beta 11
  - Windows
  - i18n (0.6.0, 0.5.0) according to "gem list"</p>
  
  <p><strong>Set-up:</strong>
  I have a multilingual website about calculations using Swedish and English as languages. I am using friendly_id to create seo-friendly url's.</p>
  
  <p>In my mysql-table I have columns "slug", "slug_se" and "slug_en". I am not sure if I need to use the "slug"-column, it is identical with "slug_en".</p>
  
  <p><strong>Problem:</strong>
  While using "update_attributes" it overwrites "slug_se" with "slug" (which by default is in English). Thus, the value in "slug" is written in "slug_se".</p>
  
  <p><strong>Trouble shooting:</strong>
   - I have Googled this issue and only found one (unanswered) forum thread on Google Forum (http://groups.google.com/group/friendly_id/browse_thread/thread/154f4a5024e23418) that was left unanswered.
   - I have tried to find alternatives to update_attributes, I could go through mysql but that really wouldn't be neat.</p>
  
  <p><strong>Questions:</strong>
   - Do I need to use the "slug"-column at all?
   - Is there an alternative to update_attributes that does not try to update the id as well?
   - Can you see anything wrong in what I am doing that is causing the problem?</p>
  
  <p><strong>Code:</strong>
  Model:</p>
  
  <pre><code>  extend FriendlyId
    friendly_id :name, :use =&gt; :slugged, :use =&gt; I18n
  </code></pre>
