When exporting contacts, a lot of informations are lost. Let's say you have a contact with 4 email addresses and 2 cellphones, after exporting that contact the LDIF file contains only two email addresses (mail and mozillasecondemail), and only one cellphone.

I think there should be an "Export as vcard" menu to export a contact (or a whole addressbook) in vcard format. How hard can that be ? You already have a "View Raw Source" menu that shows the vcard's raw source, so why not add a way to export that raw source, and the raw sources of all the contacts of an addressbook ?

I finally decided to tweak the source code and to hide the "Export" menu of the contacts or addressbooks, because it wrongfully leads the users to believe they can export or backup their addressbooks that way, which is definitely untrue, the result being incomplete. Better to have no export menu at all, rather than a buggy one.

I marked that issue as "major", because IMHO a proper export functionality should be mandatory for a CardDAV server.
