empty eps file export fails to re-import back into inkscape

Initially reported by @monikajaskolka in inbox#5440 (moved) (issue focuses on a mac specific issue).

Steps to reproduce:

1. Open a new document in Inkscape
2. Save the blank document as an EPS named drawing.eps (drawing.eps)
3. Close document
4. Open drawing.eps

What happened?

• The following error, which makes sense because no objects are inside the eps file (so -dEPSCrop fails).

What should have happened?

• A nicer error message, and maybe just attempt to open the file without cropping the eps file, even though it is non-standard

Inkscape version

• Still present in latest extensions, and Inkscape 1.2-dev (71f65390d8, 2021-08-04) Linux Mint 20
