Description
Caused by CRM-15830: when editing a contact record, it is not possible to remove all groups.
How to reproduce:
- Create a contact, add the contact to 1 group
 - Edit the contact, remove the group from the list of groups for that contact (NB: not from the 'Group' tab, that works fine).
 
Result: the contact is still in the group.
Same problem with tags.
