title: hg "stream ended unexpectedly" error on cloneing
body: <p>I'm trying to clone a bit repository from bitbucket via hg but I keep getting this error:</p>
  
  <pre><code>abort: stream ended unexpectedly (got 404093 bytes, expected 8706452)
  </code></pre>
  
  <pre>mac:~ user$ hg clone https://user2@bitbucket.org/mine/test
  http authorization required
  realm: Bitbucket.org HTTP
  user: user2
  password: 
  destination directory: test
  requesting all changes

  transaction abort!
  rollback completed
  abort: stream ended unexpectedly (got 404093 bytes, expected 8706452)
  </pre>
  
  <p>I have tried it twice now but both times it's given the same error.
  I have more than enough HDD space.</p>
  
  <p>Any thoughts?</p>
