Actually, It looks like the pipe was being introduced here..

imp/lib/Mailbox.php..

     function _cachedMailbox($mbox)
     {
         return IMP::serverString($mbox) . '|' . IMP::hideDeletedMsgs();
     }

those boxes are running RC3 (with bits from FRAMEWORK_3 to fix  
post-RC3 issues).  We're currently using imp/lib/Mailbox.php 1.76.10.68.
