I apologize in advance if this is rather convoluted or not what you  
wanted but I have no understanding of PHP and am not a software  
developer.

Here is a summary of what I did.
0-setup the PEAR/Horde/Imap/Client/Cache/Backend/Cache.php file with  
the debug statements (see below).
1-Cleared the cache backend (file system)
2-sent two messages to a test user with an empty inbox
3-login as the test user and display the inbox resulting in a debug  
file being generated.  See attachment debug-login.txt
4-marked messages for deletion and click purge deleted.  See  
attachment debug-purge.txt

To setup the debug, I changed two functions in the Cache.php file as follows:

     public function deleteMsgs($mailbox, $uids)
     {
$dmsg = "deleteMsgs-ENTRY";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);
         $slicemap = &$this->_slicemap[$mailbox];
$dmsg = "deleteMsgs-POINT-1";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);
         $deleted = array_intersect_key($slicemap['s'], array_flip($uids));
(snip)
And  further down:

     protected function _loadSliceMap($mailbox, $uidvalid = null)
     {
$dmsg = "_loadSliceMap-TOP";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);

         if (!isset($this->_slicemap[$mailbox]) &&
             (($data = $this->_cache->get($this->_getCid($mailbox,  
'slicemap'), 0)) !== false) &&
             ($slice = @unserialize($data)) &&
             is_array($slice)) {
             $this->_slicemap[$mailbox] = $slice;
         }

$dmsg = "_loadSliceMap-AFTER-IF-1";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);

         if (isset($this->_slicemap[$mailbox])) {
             $ptr = &$this->_slicemap[$mailbox];
             if (is_null($ptr['d']['uidvalid'])) {
                 $ptr['d']['uidvalid'] = $uidvalid;
$dmsg = "_loadSliceMap-RETURN-1";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);
                 return;
             } elseif (!is_null($uidvalid) &&
                       ($ptr['d']['uidvalid'] != $uidvalid)) {
                 $this->_deleteMailbox($mailbox);
             } else {
$dmsg = "_loadSliceMap-RETURN-2";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);
                 return;
             }
         }
$dmsg = "_loadSliceMap-AFTER-IF-2";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);


         $this->_slicemap[$mailbox] = array(
             // Tracking count for purposes of determining slices
             'c' => 0,
             // Metadata storage
             // By default includes UIDVALIDITY of mailbox.
             'd' => array('uidvalid' => $uidvalid),
             // The ID of the last slice.
             'i' => 0,
             // The slice list.
             's' => array()
         );
$dmsg = "_loadSliceMap-END";
Horde::debug($dmsg);
Horde::debug($this->_slicemap);

     }

It appears that when you click purge deleted, the function  
loadslicemap is not called at all.

Something tells me this is not going to be useful.  If not, please let  
me know what to change or send me a php code that has the debug  
statements you need and I will use that.
Thanks,
Aria
