title: SVN error when trying to merge from a branch
body: <p>I'm trying to merge changes from a branch to the trunk, for a single file and a single revision.</p>
  
  <p>I'm using VisualSVN as the front-end.</p>
  
  <p>So I right-click the file, Visual SVN -> Merge, then select ‘Merge a range of revisions’, then enter the revision number (from the log) and hit Next. Then I click ‘Test Merge’</p>
  
  <p>What I get is the following error:</p>
  
  <blockquote>
    <p>'<a href="http://subversion.tigris.org/xmlns/dav/md5-checksum" rel="noreferrer">http://subversion.tigris.org/xmlns/dav/md5-checksum</a>' was not present on the resource. </p>
  </blockquote>
  
  <p>Any ideas why this is happening?</p>
