Can't revoke and push new key.

I recently got a new machine, and lost my keys by accident. I generated a new key locally:

```
$ gpg --gen-key
```

Which works fine:

```
$ tree ~/.gnupg ~
.gnupg
├── gpg.conf
├── pubring.gpg
├── pubring.gpg~
├── random_seed
├── secring.gpg
└── trustdb.gpg

$ gpg -K
/home/marco/.gnupg/secring.gpg
------------------------------
sec 2048R/406F0AF9 2015-11-01
uid Marco Vermeulen
ssb 2048R/A3FF438D 2015-11-01
```

I'm logged in with the keybase cli, and then revoke:

```
$ keybase revoke
Your keybase login passphrase: ***************
- run scrypt [==================================] 100%
error: the user marcovermeulen doesn't have a local key
```

Which of course is not true as I just generated one.

When I then try the alternative of pushing my local key, it complains:

```
$ keybase push --update
info: Updating both remote keys with local version
error: `gpg` exited with code 2
warn: gpg: error reading key: secret key not available
```

I'm running on Ubuntu 15.04 with gpg 1.4.18 using ZSH 5.0.7. Keybase client installed on Node 4.2.1

Any ideas?

Start by reproducing the reported sequence with `gpg --gen-key`, `keybase revoke`, and `keybase push --update` in the stated Ubuntu, GPG, ZSH, and Node environment. Trace how the CLI checks for a local key and invokes GPG; done means the newly generated key can be revoked or pushed without the reported local-key and secret-key errors.
