I have same error on 4.8.2 and I removed teh live id and openid, restarted app and still have error. Any other course I should take? I also notice that when adding role and it giving error, though the role is added, the email isn't sent.

Thx,
Tj

PreferredLocale must also be specified.  If you are proficient with SQL, you can query for missing values using a join of the ProfilePropertyDevinition, UserProfile, and User tables. 

Although you receive an error here, note that it does not impede underlying role functionality (other than the missing e-mail).

@Mike: Will the provider update automatically insert those missing profile values that should have been inserted initially, or will this be the responsibility of the host?

Here is the SQL:

INSERT INTO UserProfile
(UserID, PropertyDefinitionID, PropertyValue, PropertyText, Visibility, LastUpdatedDate)
SELECT u.UserID, 38, 'en-US', NULL, 2, GETDATE()
FROM Users u
WHERE NOT EXISTS(SELECT * FROM UserProfile WHERE PropertyDefinitionID=38 AND UserID=u.UserID)

Replace 38 with the prop def ID of PreferredLocale and 'en-US' with the locale you want to set them to.
