title: Mercurial not configured correctly
body: <p>I have recently updated to eclipse juno. I have also updated mercurial to its latest version, but it is still giving me problems. The mercurial plugin tells :"Unsupported hg version:1.9.3. Expected is at least2.0.0." but its already updated(see pic). </p>
  
  <p>If I try to commit, it automatically opens preferences window, which gives message :"Mercurial is not configured correctly.Run 'hg debuginstall' to analyse.". </p>
  
  <p>When I do that, it says:"no username supplied". Then I run "hg -y debuginstall", which says, no problems were detected.</p>
  
  <p>Everything that I mentioned is depicted in the picture.</p>
