title: Binary file lost using svn merge
body: <p>I have two branch (let say branch A and branch B)in my svn repository
  I'm done with one of them, branch B
  I want to get changes of the other branch ,branch A.
  On both branch i have binary files,in a separated folder.
  When i try to get the new binary files of branch A, i get nothing, just tree conflict.</p>
  
  <p>I use subclipse, merge a range of revision.
  The branches was created with svn 1.4. Since the repository was moved to svn 1.6.</p>
