Importing grades via the CSV File grade import results in the following message being displayed:

You need to update your sql to include additional name fields in the user object.

* line 3551 of /lib/moodlelib.php: call to debugging()

* line 155 of /grade/import/lib.php: call to fullname()

* line 119 of /grade/import/csv/index.php: call to grade_import_commit()

It appears that the get_unenrolled_users_in_import() function in grade/import/lib.php doesn't include all of the required fields following the extension of additional name fields.
