title: SVN says file is in version control when it isnt
body: <p>I run 'svn status' and I get</p>
  
  <pre><code>?      app/views/ad_report
  </code></pre>
  
  <p>But when I try to run 'svn add app/views/ad_report', it says it's already in version control, but status just said it isn't.</p>
  
  <pre><code>svn: warning: 'app/views/ad_report' is already under version control
  </code></pre>
  
  <p>There is a folder with the same name in a different path, 'app/views/backend/ad_report', but there are a lot of same folder names, but different path in this repo, and all those have been added.</p>
  
  <p>Is svn getting these two folders mixed up? How do I get around this?</p>
