title: SVN commit fails: File already exists
body: <p>I've got a file (mapViewController.m) which is in svn but I cannot commit changes to it. I tried to copy the file elsewhere and then update. The file does not come with the update so I copy it back. Then I can't commit changes to it.</p>
  
  <p>This is hard to explain what is wrong... because I don't know. </p>
