Here comes a

I also have a horde_debug.txt which has about 16,000 lines. If this  
helps you I could send it to you directly.

My IMAP-Server is cyrus-imapd (Version: 2.2.13-19+squeeze3)

Here is everything about session in Horde's conf.php:
$conf['session']['name'] = 'Horde';
$conf['session']['use_only_cookies'] = true;
$conf['session']['cache_limiter'] = 'nocache';
$conf['session']['timeout'] = 0;
$conf['session']['max_time'] = 0;
$conf['sessionhandler']['type'] = 'Builtin';
$conf['sessionhandler']['memcache'] = true;

And the like for cache:
$conf['session']['cache_limiter'] = 'nocache';
$conf['share']['cache'] = true;
$conf['cache']['default_lifetime'] = 86400;
$conf['cache']['driver'] = 'Memcache';
$conf['cache']['compress'] = true;
$conf['cache']['use_memorycache'] = '';
$conf['cachecssparams']['driver'] = 'filesystem';
$conf['cachecssparams']['lifetime'] = 86400;
$conf['cachecssparams']['compress'] = 'php';
$conf['cachecss'] = true;
$conf['cachejsparams']['driver'] = 'filesystem';
$conf['cachejsparams']['compress'] = 'php';
$conf['cachejsparams']['lifetime'] = 86400;
$conf['cachejs'] = true;
$conf['cachethemesparams']['check'] = 'appversion';
$conf['cachethemesparams']['lifetime'] = 604800;
$conf['cachethemes'] = 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;

For caching PHP in general I use the pecl-package APC Version 3.1.9.

You said that it would be the best way to help if I found in the code  
where the error happens. Could you maybe advise me where to start?
