nested copies broken on trunk

Hi,

the attached script breaks the working copy beyond repair:

  + rm -rf nested-copy
  + mkdir -p nested-copy
  + mkdir -p nested-copy/trunk
  + mkdir nested-copy/trunk/gamma
  + echo delta
  + > nested-copy/trunk/gamma/delta
  + svnadmin create /tmp/nested-copy/repos
  + svn import nested-copy/trunk file:////tmp/nested-copy/repos/trunk -m importing project tree
  Adding nested-copy/trunk/gamma
  Adding nested-copy/trunk/gamma/delta
  
  Committed revision 1.
  + rm -rf nested-copy/trunk
  + svn checkout file:////tmp/nested-copy/repos/trunk nested-copy/trunk
  A nested-copy/trunk/gamma
  A nested-copy/trunk/gamma/delta
  Checked out revision 1.
  + svn cp nested-copy/trunk/gamma nested-copy/trunk/gamma.copied
  A nested-copy/trunk/gamma.copied
  + svn mv nested-copy/trunk/gamma.copied/delta nested-copy/trunk/gamma.copied/delta.copied
  A nested-copy/trunk/gamma.copied/delta.copied
  D nested-copy/trunk/gamma.copied/delta
  + svn commit -m this commit breaks the WC nested-copy/trunk
  Adding nested-copy/trunk/gamma.copied
  Deleting nested-copy/trunk/gamma.copied/delta
  Adding nested-copy/trunk/gamma.copied/delta.copied
