Comment 4 for bug 306438

Nominating again because mistakes will still occur even with a warning "Are you
sure you want to delete the selected address book?".

For instance, the user is in a hurry and might think that they have a card
selected and when they delete they may not read the warning completely. They OK
through the warning and then realize that they deleted the entire address book!
There is no way to recover from this. An undo would help greatly in these
situations.
