Original report

Uploading users via csv file does not give a warning status if country column contains real country names rather than country codes. Submitting the file with full country names results in a misleading 'Error writing to database' message.

Addendum

The above has been resolved, there is no longer a DML exception throw because of automatic cleaning of the uploaded data

However, there is no indication given to the user which data is invalid and is being automatically cleaned:

This makes it very hard for a user to actually fix the file content (because they don't know what's broken in it). We should fix that, hence re-opening
