title: SVN command returned with the following error
body: <p>When I want to commit my project to SVN, the following error pops out: </p>
  
  <pre><code>org.tigris.subversion.javahl.ClientException:
  Working copy '/media/Data/NETBEANS_PROJECTS/myproject/web/pages/ajax-fragments' locked; try performing 'cleanup'
  </code></pre>
  
  <p>I use NetBeans 7.1 (tried with 7.0.1 and 6.9, the same) and CollabNet Subversion control plugin. What he wants to tell me with 'cleanup'?</p>
