title: Tortoise SVN Error on commit: 'Invalid PROPPATCH property'
body: <p>I'm using tortoise svn 1.6.16 on a Windows 7 machine, and getting an error on commit, as below:</p>
  
  <pre><code>Error: Commit failed (details follow):  
  Error: At least one property change failed; repository is unchanged  
  Error: Invalid PROPPATCH property  
  </code></pre>
  
  <p><a href="https://stackoverflow.com/questions/11086570/svn-error-setting-property-log-could-not-execute-proppatch">A previous question asked here</a> indicated that this was due to quotes in the commit message, but that is not my issue.</p>
  
  <p>I've tried re-installing svn, and have also tried making my changes a second time on a clean checkout of my project. The error still persists though.</p>
  
  <p>Can anyone recommend a way to access the invalid PROPPATCH property and fix it? Or is there a known workaround to get me over this hump? Any info much appreciated.</p>
