title: Mercurial error 255 - how to revive my repository?
body: <p>it's a quesion about mercurial.</p>
  
  <p>I'm not a unix - guy, but use a mercurial together with MacHG for my development on Mac. Yesterday I had to change my mac, I just copied my project folder with repository on new mac, but now I can't do anything with it in mercurial. I can open project in xcode and everuthing is fine, but if I try to do anything in mercurial via terminal I'm getting this: <code>abort: data/.DS_Store.i@e959df7694ce: no node!</code></p>
  
  <p>If I try to do anything in MacHG I'm getting <code>Mercurial reported error number 255:
  skipping unreadable ignore file '/Users/zakhar/.hgignore': No such file or directory
  abort: data/.DS_Store.i@e959df7694ce: no node!</code></p>
  
  <p>What can I do? where can I get this .hgignore file? I don't have old mac any more.</p>
