Can't track one user

I’m "timbray" and at https://keybase.io/timbray it says I’m tracking "paulehoffman" and "ericajoy". If I say

keybase encrypt ericajoy -m 'alpha beta gamma'

it goes ahead, lists the proofs, says I’ve OK’ed then, and creates the mesage

If I say

keybase encrypt paulehoffman -m 'alpha beta gamma'

Is this the paulehoffman you wanted? [y/N]

So for some reason, the "track" operation isn't working in this case.

Hint: Paul used his own GPG key, he told me.

Start by reproducing the two reported `keybase encrypt` commands and compare their tracking and identity-proof behavior, using the Keybase profile and GPG-key detail in the report as context. Trace the `track` operation and encryption command path; done means a tracked user no longer prompts for confirmation when the tracked identity is valid, with regression coverage for this case.
