Merge patients is broken

Pick any two patients and merge them, and you'll get the error below.
(At this point one of the patients will have been voided, and the other will have had lots of data moved over. If you search for the ID number mentioned in the stack trace via the UI you'll see two rows of the patient. But the database will only show one row in patient_identifier with that identifier.)

An Internal Error has Occured
org.openmrs.api.IdentifierNotUniqueException

Identifier 2333EG-2 already in use by patient TRAC-2334

Consult the help document.
Contact your friendly neighborhood administrator if it cannot be resolved.
