[horde] ActiveSync does not work after update to 2.0.0beta4

[Samuel Wolf]

Hi,

I can not use activesync any more (account error) after update to 2.0.0beta4.

pear install horde/Horde_ActiveSync
horde/Horde_ActiveSync is already installed and is the same as the
released version 2.0.0beta4
install failed

$conf['activesync']['emailsync'] = true;
$conf['activesync']['version'] = '12.1';
$conf['activesync']['autodiscovery'] = 'user';
$conf['activesync']['logging']['path'] = '/tmp/activesync.log';
$conf['activesync']['logging']['type'] = 'custom';
$conf['activesync']['ping']['heartbeatmin'] = 60;
$conf['activesync']['ping']['heartbeatmax'] = 2700;
$conf['activesync']['ping']['heartbeatdefault'] = 480;
$conf['activesync']['ping']['deviceping'] = true;
$conf['activesync']['ping']['waitinterval'] = 5;
$conf['activesync']['enabled'] = true;

Apache access log show the connection:
80.187.xxx.xxx - samuel [13/Oct/2012:20:31:52 +0200] "POST

HTTP/1.1" 500 1719 "-" "Moto-XT910/6.5.1"

But the log file is empty:
root at wds:/tmp# cat activesync.log
