title: CollabNet SVN won't dump a repository
body: <p>For an unknown reason, <em>Collabnet SVN</em> will not dump some of my the repositories, although the others it dumps correctly. The problem is observed with both manual dumps via <code>Repositories-&gt;Dump</code> and automatic ones via <code>Repositories-&gt;Backup Schedule</code>. In both cases, the job appears under <em>Finished Background Jobs</em> with a zero execution time—the <em>Started at</em> and <em>Finished at</em> fields are the same.</p>
  
  <p>Why can this happen? The affected repositories are not empty, contain revisions, and I am not specifying any specific range on the dump page, expecting <em>SVN</em> to dump it entire. A manual invocation of <code>svnadmin dump</code> works well, but I should like to use the backup scheduler available through the web-interface instead of writing my own.</p>
