title: Error with git rebase ("could not apply...")
body: <p>I'm the administrator of the GitHub repository <a href="https://github.com/plison/opendial">https://github.com/plison/opendial</a>. I would like to reduce the number of commits on the repository, since the repository already has a few thousand commits, many of whom are minor debugging changes that could easily be squashed together (especially the ones that are a few years old).</p>
  
  <p>I'm therefore trying to apply rebasing in order to squash together part of my commits. However, I've experience the following issue:</p>
  
  <ol>
  <li>When I type e.g. <code>git rebase -i HEAD~10</code>, I get a quite long number of commit lines (much more than 10) in the interactive editor. What could be the reason?</li>
  <li>More importantly, once I close the interactive editor to start the rebasing, I systematically get the error message "error:could not apply ', <strong>even when I do not make any change to the commits</strong> (i.e. if I leave all lines as 'pick', without any modification or reordering).</li>
  </ol>
  
  <p>How can I solve these issues? It should be noted that the repository was automatically imported from a previous (SVN) repository hosted on Google Code. The conversion seemed so far to have worked well, but I'm wondering why I get these errors when trying to rebase my commits.</p>
