title: Issue converting mercurial repository to subversion on windows7 64 bit and Ubuntu
body: <p>I want to convert a mercurial repository into subversion (I know, I know) but the standard answer for this <a href="https://stackoverflow.com/questions/1898994/converting-from-mercurial-to-subversion">Converting from Mercurial to Subversion</a> doesn't seem to work for me.  I have installed tortoiseHg and the svn command line package from collabnet.  Any ideas or tips?</p>
  
  <pre><code>D:\work\horizon&gt;hg convert --dest-type svn src horizon-svn --debug --traceback
  initializing svn repository 'horizon-svn'
  running: "svnadmin" "create" "D:\work\horizon\horizon-svn" &lt; NUL:
