title: Info about parameters and rendered partials missing from Rails development log file
body: <p>This is how a normal Rails 3.2 log file entry looks like:</p>
  
  <pre><code>Started GET "/admin" for 127.0.0.1 at 2013-08-05 14:36:43 +0200  
  Processing by Admin::PagesController#show as HTML  
    Parameters: {"id"=&gt;"admin/dashboard"}  
    Post Load (1.5ms)  SELECT 'posts'.* FROM 'posts' WHERE 'posts'.'riddle' = 1 AND 'posts'.'solved_at' &lt;= '2013-08-05 12:36:43' ORDER BY comments_count DESC LIMIT 1  
    [...]  
    CACHE (0.0ms)  SELECT 'comments'.* FROM 'comments' WHERE 'comments'.'post_id' = 74 ORDER BY 'comments'.'id' DESC LIMIT 1  
     (0.3ms)  SELECT COUNT(*) FROM 'posts' WHERE 'posts'.'riddle' = 1  
    Rendered admin/dashboard.html.haml within layouts/admin (109.1ms)  
    Rendered shared/admin/_header.html.haml (3.8ms)  
  </code></pre>
  
  <p><strong>The problem: in one of my apps, the leading <code>Processing ...</code> and <code>Parameters: ...</code> and trailing <code>Rendered ...</code> lines are missing and I can't for the life of me figure out why!</strong></p>
  
  <pre><code>Started GET "/admin" for 127.0.0.1 at 2013-08-05 14:36:43 +0200  
    Post Load (1.5ms)  SELECT 'posts'.* FROM 'posts' WHERE 'posts'.'riddle' = 1 AND 'posts'.'solved_at' &lt;= '2013-08-05 12:36:43' ORDER BY comments_count DESC LIMIT 1  
    [...]  
    CACHE (0.0ms)  SELECT 'comments'.* FROM 'comments' WHERE 'comments'.'post_id' = 74 ORDER BY 'comments'.'id' DESC LIMIT 1  
     (0.3ms)  SELECT COUNT(*) FROM 'posts' WHERE 'posts'.'riddle' = 1  
  </code></pre>
  
  <p>The app is too big and includes too many gems to post relevant parts here, but I tried removing gems in development, verified that the log level is set to <code>:debug</code>, the logger is the standard one etc.</p>
  
  <p>Has anyone seen this before?</p>
