title: Subversion Repository Error
body: <p>This one has me scratching my head.</p>
  
  <p>I'm running Subversion 1.3.1 (r19032) on Ubuntu. All was well until recently when I tried to run svnadmin verify prior to a dump. This is the error message:</p>
  
  <blockquote>
    <p>svnadmin: Invalid diff stream: insn 0
    cannot be decoded</p>
  </blockquote>
  
  <p>I have looked around for an explanation and fix but can't seem to find one. Subversion experts, I need your help.</p>
