body: <p>I've just upgraded to the newer version of redmine (1.1.3) , after that all my mercurial repositories shown "Entry and/or revision doesn't exist in the repository."</p>
  
  <p>something goes wrong, but what?</p>
  
  <p>the permissions, settings and paths of repositories are the same.</p>
