Folks package warnings while running gnome-contacts

[Saurabh Patel <srp201201051 gmail com>]

    I'm having folks related warnings while running gnome-contacts. Plus because of this when I try to add mew contact, input fields for address are not shown and after clicking 'Create new contact', the new contact is not added to contact list.

I've installed evolution-mail in my laptop. I'm using ubuntu 13.10.

Warnings are pasted on this link.
