title: removing broken names in Git (dropbox conflicted copy)
body: <p>I save my repo in dropbox, and one day (see date below) it went crazy. Now I get these warning every time I try to autocomplete a branch name</p>
  
  <pre><code>warning: ignoring ref with broken name refs/heads/develop (MacBook Pro's conflicted copy 2015-02-28)
  warning: ignoring ref with broken name refs/heads/master (MacBook Pro's conflicted copy 2015-02-28)
  warning: ignoring ref with broken name refs/remotes/origin/develop (MacBook Pro's conflicted copy 2015-02-28)
  warning: ignoring ref with broken name refs/remotes/origin/master (MacBook Pro's conflicted copy 2015-02-28)
  warning: ignoring ref with broken name refs/remotes/production/master (MacBook Pro's conflicted copy 2015-02-28)
  </code></pre>
  
  <p>How do I fix these warning?</p>
  
  <p><strong>Note: For all the duplicate-trigger-happy people - this is not a dup! I just want to remove the references above to stop getting the warning. The git repo is intact</strong></p>
