[SyncEvolution] N900+funambol+zimbra todo and calendar

Hello I'm having some problems getting syncevolution on the Nokia N900 to sync with my funambol server and Zimbra. Contacts work fine, but tasks and calendar don't sync down from the server (but from phone to server is OK). I'm getting the following error: [event] Status:'UNSUPPORTED MEDIA TYPE' for a 'Add' for this items on funambol, while syncevolution reports a successful sync. The more I look in to this, the more I think my syncevolution configuration may not in fact be the problem, but the only real hints I've been able to dig up point at the 'type =' parameter in config.ini here: http://forums.internettablettalk.com/showthread.php?p=546066#post546066 type is currently set to type = todo:text/calendar! for tasks (as per the configuration template) and type = calendar:text/calendar! for calendar events. I've tried the other maemo backends with various levels of success (all error out on the funambol side). Anyone have any further tips where I could look? Anyone have zimbra and an N900 syncing? Thanks, Aaron Krebs
