2.2.5 (with the 2.2.6 3 file fixup). I think the problem is in the following code somewhere:

if ($bbuserinfo[pmfolders]) {
    $allfolders = split("\n", trim($bbuserinfo[pmfolders]));
    $foldercount = 0;
    while (list($key,$val)=each($allfolders)) {
      $folder = split("\|\|\|", $val);
      $foldercount++;
      $highestnum = $folder[0];

      $folder[folderid]=$folder[0]+1;
      $folder[title]=$folder[1];
eval("\$folderboxeshack .= \"".gettemplate("priv_showfolders_folderbit_hack",1,0)."\";");
      }
  }

or here:

 $highestnum = 0;
  $hiddenfolderboxes="";

  if ($bbuserinfo[pmfolders]) {
    $allfolders = split("\n", trim($bbuserinfo[pmfolders]));
    $foldercount = 0;
    while (list($key,$val)=each($allfolders)) {
      $folder = split("\|\|\|", $val);
      $foldercount++;
      $highestnum = $folder[0];

      $folder[folderid]=$folder[0]+1;
      $folder[title]=$folder[1];
      eval("\$hiddenfolderboxes .= \"".gettemplate("priv_showfolders_folderbit_hidden",1,0)."\";");
    }
  }

  $foldercount=0;
  while ($foldercount<1) {
    $foldercount++;

    $folder[folderid]=$foldercount+$highestnum+1;
    $folder[title]="";
    eval("\$newfolderboxes .= \"".gettemplate("priv_showfolders_folderbit_add",1,0)."\";");
  }
  $hiddenfolderboxes .= "<INPUT TYPE=\"hidden\" name=\"highest\" value=\"".($highestnum+3)."\">";
