That code is running perfect.  There is no VANISHED response, so no  
messages have been deleted between those MODSEQs according to the  
server.

I can verify this works fine on my server.  E.g.:

C: 4 UID FETCH 1:* UID (VANISHED CHANGEDSINCE 34240)
S: * VANISHED (EARLIER) 14199,14239,14242
S: * 37 FETCH (UID 14211 MODSEQ (34251))
S: * 38 FETCH (UID 14212 MODSEQ (34250))
S: * 39 FETCH (UID 14243 MODSEQ (34249))
S: 4 OK Fetch complete

Shot in the dark: try this change in _vanished():

         $cmd = $this->_clientCommand(array(
             'UID',
             'FETCH',
             $ids->all ? '1:*' : strval($ids),
-           'UID',
+           new Horde_Imap_Client_Data_Format_List('UID'),
             new Horde_Imap_Client_Data_Format_List(array(
                 'VANISHED',
                 'CHANGEDSINCE',
                 new Horde_Imap_Client_Data_Format_Number($modseq)
             ))
         ));
