CardDav not saving new contacts from external access.

[AbsoluteMonkey]

When I try and save a new contact from my BB or from Evolution it does not save the new contact.
I can save a new contact via the webmail zimbra portal.
I can however edit contacts just fine. If I edit a contact on my BB then it syncs across the other portals just fine. However new contacts I get nothing.
Here's a snippet from my logs.

Index issue?

This is Bug https://bugzilla.zimbra.com/show_bug.cgi?id=84246 - Create Contact via CardDAV requires If-None-Match header.



Those clients are not specifying an If-None-Match header and Zimbra is requiring that header - although it is a SHOULD rather than a MUST in RFC6352 the specification for CardDAV.
