title: xcode does not show files in the commit window
body: <p>I have checked out a copy of a SVN project, I have modified some files and want to commit the changes. If I go to File &gt; Source Control &gt; Commit. I see an empty list and a button saying &quot;Commit X files&quot;. I expected a list of the modified files.</p>
  <p>Now, I use the command line tool (svn ...). But I want to bring back the Xcode commit window.
  How may I fix it?</p>
  <p>BTW. I'm using Xcode 4.6.1</p>
