Can't generate key

I'm unable to generate a key on Linux using the following command

```bash
$ keybase pgp gen --multi
```

When run the command is asked for a username and email (multiple times), the second time that the email is ask, the program do not accept an and ends with the error: `ERROR Login required: LoadPassphraseState`

Start by reproducing `keybase pgp gen --multi` on Linux and tracing the `LoadPassphraseState` error. Check how the command handles the repeated email prompt; done means the prompt accepts the input and key generation completes without the login-required error.
