Arrived to my grand mother, I drag and drop her to the list, and see that "1 contact is copied", but she didn't appear in the list, because she has no email address. Reproducible: Always Steps to Reproduce: 1. Create an empty list 2. Create a contact with no email address 3. Drag and drop this contact to the list 4. Look at the message displayed in the status bar Actual Results: The status bar display that "1 contact was copy" whereas it was not Expected Results: A warning should be displayed (at least in the status bar) telling me that this contact cannot be added to the list because it hasn't an email address. This should also deal with the case where I can select multiple contacts, some with email address and other without.
