Description

I installed the latest version of Atom. Since I am on my business laptop I don't have admin permissions but I never was asked for them so there shouldn't be a problem with it.
When I then open the GitHub Pane and enter the Token from github.atom.io/login I get the following error message:

TypeError: Cannot read property ‚split‘ of null at GithubLoginModel.getScopes (C:Users\myName\AppData\Local\atom\app-1.43.0\resources\app\static<embedded>:14:627754)

Steps to Reproduce

1. Click the link to github.atom.io/login in GitHub Pane
2. Copy the token from the website
3. Paste the token into the field in the pane
4. Get the error message from above

Expected behavior:

That my GitHub profile is linked

Actual behavior:

I only get the message. I push commits not with my GitHub user name but with my laptops display name. That's weird because actually my project is private...?

Reproduces how often:

Always

Versions

Atom : 1.43.0
Electron: 4.2.7
Chrome : 69.0.3497.128
Node : 10.11.0

Win7 64-bit Client v4.0 with Service Pack 1

Additional Information

It's kind of a portable version...
