title: Unable to create branches on Subversion repository using TortoiseSVN
body: <p>I have pulled down a completely fresh checkout of our Subversion repository. Next I right click on the working folder and select "Branch/Tag". I give the branch a name, and select to have the copy made from my working copy. I also select to switch the working copy to the new branch.</p>
  
  <p>When I click OK, I receive the following error:</p>
  
  <pre><code>Commit failed (details follow): 
  Directory 'C:\Projects\StrattonWF_2' is out of date
  File not found: transaction '8877-59x', path 
  '/branches/foo/bar/'
  You have to update your working copy first.
  </code></pre>
  
  <p>However, following the instructions in the error message and updating the working copy does not help - the error keeps happening.</p>
  
  <p>This is only happening on my workstation - noone else has this issue. I can also do commits to the trunk fine. Like I said, I have pulled down a completely fresh copy of the trunk.</p>
  
  <p>What else can I try?</p>
  
  <p>The relevant version numbers are:</p>
  
  <ul>
  <li>TortoiseSVN 1.8.4</li>
  <li>Subversion 1.8.5</li>
  <li>Client operating system: Windows XP</li>
  </ul>
