Nothing echoes back to Atom (Atom 1.8.0, Nvim 0.1.5)

[gwerbin]

Following the instructions, I'm able to type in commands and move around just fine, except for the fact that the Atom window itself is blank -- everything is happening on the Neovim side and nothing is getting echoed back.

This is what appears in the Electron console:
