Uncaught TypeError: Cannot read property 'emit' of null

[dniku]

The issue randomly occurred right after I saved a file I was editing (specifically, this one). I don't know of any sequence of steps that would reproduce it.

Atom: 1.16.0 x64 Electron: 1.4.15 OS: "Manjaro Linux" Thrown From: haskell-ghc-mod package 1.19.9

Eh. This shouldn't be possible. Quite literally. I have no idea on how you managed to do that.
