Atom tries to delete undefined file when no file is selected

This is Atom 1.4.0 on OS X 10.10.5.

Reproduce/What does happen:
Select a file in the file tree. Press Fn-Delete; atom will show a delete alert. Click Move to Trash. The once-selected file is deleted and no file is selected. Press Fn-Delete again; atom will show a delete alert but with no file name. Click either Cancel or Move to Trash and the alert will disappear with no effect.

What should happen:
Not completely sure, but probably the Fn-Delete press should be ignored.
