[horde] Trouble with imp using memcache server

[Luis Felipe Marzagao]

Hello:

(horde) 3.3.9-cvs
(imp) H3 (4.3.8-cvs)

My memcache server seems to be working just fine:

[root at centos ~]# telnet localhost 11211
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
stats
STAT pid 6324
STAT uptime 6764
STAT time 1280095475
STAT version 1.4.5
...

I also run this test script
(http://www.php.net/manual/en/memcache.installation.php#85770), and
the results seem just fine:

[root at centos Desktop]# php test.php
Server's version: 1.4.5<br/>
Store data in the cache (data will expire in 10 seconds)<br/>
Data from the cache:<br/>
object(stdClass)#3 (2) {
  ["str_attr"]=>
  string(4) "test"
  ["int_attr"]=>
  int(123)
}

My Horde configuration is like this:

[root at centos config]# grep -i cache conf.php
$conf['session']['cache_limiter'] = 'nocache';
$conf['group']['cache'] = false;
$conf['share']['cache'] = false;
$conf['cache']['default_lifetime'] = 86400;
$conf['cache']['driver'] = 'memcache';
$conf['sessionhandler']['memcache'] = true;
$conf['memcache']['hostspec'] = array('localhost');
$conf['memcache']['port'] = array('11211');
$conf['memcache']['weight'] = array();
$conf['memcache']['persistent'] = false;
$conf['memcache']['compression'] = false;
$conf['memcache']['large_items'] = true;
$conf['memcache']['enabled'] = true;

But when I use IMP, horde's log starts to show these msgs:

Jul 25 19:10:57 HORDE [error] [imp] Could not save the compiled
template file'/var/www/html/horde/config/../imp/templates/mailbox/message_headers.html'.

Any pointers?

Thanks a lot,
