_Edited by @Ben3eeE to add steps to reproduce_

1. Right click on an untitled buffer
2. Click on view unstaged changes or view staged changes

Note: There is a different exception now when doing these steps not the startsWith of undefined:

Thanks for the report! We can best provide help in English since that allows more people to look at the issue.

Can you confirm a few things for us?

• what were you doing at the time of the error?
• is the error is reproducible?
• if reproducible, do you see the error in safe mode (atom --safe)?

Oh interesting - not sure if that's actually causing the error but we can leave this open for a little while longer in case others run into the same error.

I got this error by right clicking in the blank space of a file and clicking view staged changes/view unstaged changes.

@XDelta

• Can you clarify what you mean with the blank space of a file?
• Is the error reproducible?
• Can you record a gif or screencap of reproducing the error?
