When debugging is inactive, FLAGS.SILENT is sent to update the flags  
instead of FLAGS.  This means that flag changes (FETCH responses)  
won't be returned by the server.  Which means we normally wouldn't  
update the cache...

...except this is all known behavior.  And irrelevant.  We only cache  
flags if CONDSTORE/QRESYNC is available.  If these are available and  
active, then flag changes MUST always be sent regardless of whether  
.SILENT is given (RFC 4551 [3.2]).  So my guess is that the server is  
broken because it is not sending back these FETCH responses.

The only way to be able to log this will be to alter the  
Horde_Imap_Client_Socket source (around line 3012):

         if (!empty($options['replace'])) {
             $cmd->add(array(
-               'FLAGS' . ($this->_debug->debug ? '' : '.SILENT'),
+               'FLAGS.SILENT',
                $options['replace']
             ));
             $cmds[] = $cmd;
         } else {
             foreach (array('add' => '+', 'remove' => '-') as $k => $v) {
                 if (!empty($options[$k])) {
                     $cmdtmp = clone $cmd;
                     $cmdtmp->add(array(
-                       $v . 'FLAGS' . ($this->_debug->debug ? '' :  
'.SILENT'),
+                      $v . 'FLAGS.SILENT',
                         $options[$k]
                     ));
                     $cmds[] = $cmdtmp;
                 }
             }
         }

Additionally, you can send me the IMAP log you have that was  
successful so I can check on things like CAPABILITY on your server.
