Thanks for the report! I wasn't able to reproduce with your steps - can you confirm if the error is reproducible in safe mode (atom --safe)?

Also, can you clarify this step?

2. Without quitting Atom, close the file and rename to anything with spaces

I renamed the file outside of Atom (from the command line specifically), is that what you did too?

[ChengmingLu]

To clarify step 2, I kept Atom open but closed the file, then I renamed the file from ReadMe.md to something like Read Me First.md and that's basically what step 2 means.

After that I dragged the renamed file to Atom to reopen it. Then I toggled Markdown Preview, nothing happened(preview did not show up). Finally I closed the file again and the error message showed up. Note that after the renamed file has been closed, Atom's title bar showed the filename before it was renamed.

Unfortunately like you said, even I could not reliably reproduce the issue with these steps myself. (Maybe I should not have treated these steps as "steps to reproduce", but "steps that originally caused the issue" rather)
