CLI - Segfault while encrypting

Getting "segmentation fault" when encrypting with the CLI

```
% keybase encrypt -m "Yo: " drnic
info: ...checking identity proofs
✔ public key fingerprint: 579B 1C80 9EDB CBED 8B86 9BDC 0B92 A265 A092 1641
✔ "drnic" on twitter: https://twitter.com/drnic/status/621374157616480256
✔ "drnic" on github: https://gist.github.com/df629668a531b193985a
[1] 9110 segmentation fault keybase encrypt -m "Yo: " drnic
```

Same happens when using here documents

```
% keybase encrypt drnic << EOF <<<
heredoc> Yo
heredoc> EOF

% keybase --version
0.7.9

% gpg --version
gpg (GnuPG) 1.4.19

% node -v
v0.12.4

No source files or tests are identified. Start by reproducing the crash with the reported `keybase encrypt` commands on version 0.7.9, then inspect the CLI encryption entry point and relevant runtime logs; done means encryption completes without a segmentation fault for both message and here-document input.
