Cannot delete account: "DB error"

I can't delete my account, "vorophobe@gmail.com".
I'm using this page: https://keybase.io/account/delete_me
It gives me the error message: "Error In Deletion: DB error"

Start by reproducing the failure from https://keybase.io/account/delete_me using the reported account-deletion flow, and trace where the generic "DB error" is produced. Done means the account can be deleted successfully without that error; the issue does not identify a source file or test to run.
