Import custom address fields causes db constraint error

I have set up an address custom field called 'status' with multi-select fields "Current" "Returned" and "Invalid".

When I try to import a CSV file with the status field I get the following error.

The CSV file is very simple--just two columns: The external ID and the address status field.

All address statuses in this file are either "Current" or "Returned".

The error and backtrace:
