When editing an entity with a name attribute and a unique constraint (meaning the url /etype/value_of_name will work), if you edit the name attribute and hit Apply, you get redirected to /etype/old_value_of_name?vid=edition which will generally cause an error because no such entity exist.
The Apply button should redirect to a safe url using the eid of the entity.
This bug has probably been there for a long time.
