Uncaught TypeError: Cannot read property 'is' of null

Atom Version: 0.156.0 System: linux 3.14.26-1-lts Thrown From: tree-view-open-files package, v0.1.9

Steps To Reproduce

1. open an atom project with the tree view hidden
2. press `ctrl+' on linux to open the tree view

btw: pressing ctrl+0 opens the tree view w/o error and after that ctr+\ works as well
