Import from Keybase to GPG your new keybase key

The suggestion on https://keybase.io/encrypt "using keybase track, which imports to GPG and also audits and displays identity proofs" does not work for your on key... "error: Cannot track yourself"

Start by reproducing the instructions linked from https://keybase.io/encrypt, focusing on the reported "Cannot track yourself" error during the Keybase-to-GPG import flow. Trace the tracking and import entry points reached by that workflow, then verify the suggested process works for a newly created key without producing the self-tracking error.
