The problem with an new card for an entry in a mailing list also occurs if only one address book is used and the added address is an additional email address of an existing contact.
TB (I use TB17 on Win8) will make a new card with the additional address as primary address.

The feature of adding additional addresses to a card becomes obolete. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/711322 Title: Address Book - Adding contacts to a list via List Properties results in duplicate contact entries in the list To manage notifications about this bug go to: https://bugs.launchpad.net/thunderbird/+bug/711322/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
