[sync] activeSync: time stamp problem?

[Jens-U. Mozdzen]

Hi,

when I add a new entry on my mobile device, I see the following  
ActiveSync trace and the new task is not added to my Kolab task list:

Horde_Core_ActiveSync_Driver::changeMessage(@Tasks@, )

In Apache's error log, the following corresponding message is logged:

==> /var/log/apache2/error_log <==
[Tue Dec 18 17:34:12 2012] [error] [client 192.168.*.*] PHP Fatal  
error:  Call to a member function timestamp() on a non-object in  
/srv/www/htdocs/horde5/nag/lib/Task.php on line 1377

The error occurs in the following code:
1350     /**
1351      * Create a nag Task object from an activesync message
1352      *
1353      * @param Horde_ActiveSync_Message_Task $message  The task object
1354      */
1355     public function fromASTask(Horde_ActiveSync_Message_Task $message)
1356     {
[...]
1375         /* Due Date */
1376         if ($due = $message->utcduedate || $due = $message->duedate) {
1377             $this->due = $due->timestamp();
1378         }

Anything that catches the experienced eye?

Regards,
Jens
