I do not think this is a duplicated bug, since there is 3 ways to delete contact.
1 - You can delete using the swiping gesture;
2 - Selecting the contact with long press and clicking on delete button on toolbar;
3 - Open contact details and click on delete button on toolbar;
The bug #1213046, only describes the behavior for case 1.
