Calendar sync is working, but address book sync is not, i can tell from the logs of thunderbird and the webserver that the vcf files are downloaded.. but no contacts appear in my adressbook..

Server is tine20.

Adressbook sync with my andorid devices is working fine.

I see the following errors in the Thunderbird log:

[Exception...
