TypeError: unsupported operand type(s) for +: 'int' and 'str'

[fjgonzalezm]

I was processing a large list of image files and I was getting the error 'TypeError: unsupported operand type(s) for +: 'int' and 'str''. This is the complete output:

Opening: /Users/familypc/Desktop/culprit.jpg
Traceback (most recent call last):
  File "./EXIF.py", line 132, in <module>
    main()
  File "./EXIF.py", line 100, in main
    data = process_file(file, stop_tag=stop_tag, details=detailed, strict=strict, debug=debug)
  File "/private/tmp/exif-py/exifread/__init__.py", line 201, in process_file
    hdr.dump_IFD(exif_off.values[0], 'EXIF', stop_tag=stop_tag)
  File "/private/tmp/exif-py/exifread/classes.py", line 124, in dump_IFD
    entries = self.s2n(ifd, 2)
  File "/private/tmp/exif-py/exifread/classes.py", line 71, in s2n
    self.file.seek(self.offset + offset)
TypeError: unsupported operand type(s) for +: 'int' and 'str'

I was able to track the issue to a particular file:

That file was an Photoshop export from a Nikon RAW image (*.nef) to jpg. I don't know what's wrong with it. I have other files exported the same way and I didn't have issues. The files is perfectly fine because I can open it.

My gut says this is related to issue #33 which I just submitted. After finding my issue I looked here and was able to recreate this issue with the example image above.

@fjgonzalezm , would you allow this image to be added to the sample images repo for testing?

TIA,

ianaré

[fjgonzalezm]

Yes sure you my consent to use the image

[ianare]

OK thank you

unrelated, I saw @altendky used python3, souldn't you update your setup.py classifier accordingly?

caniusepython3.com said me you don't support python3.

[ianare]

Should be fixed now (sorry for the wait).
