Exif tag 'IptcNaaInfo' (33723) causes crash when saving TIFF as JPEG ('TypeError: object of type 'int' has no len()')

[gverm]

What did you do?

Opened TIFF image, grabbed exif, tried to save TIFF as JPEG with exif.

What did you expect to happen?

JPEG to be saved successfully.

What actually happened?

Crash: TypeError: object of type 'int' has no len()

What are your OS, Python and Pillow versions?

• OS: EndeavourOS
• Python: 3.10 & 3.11
• Pillow: 9.4.0 and current git

from PIL import Image, ExifTags, TiffImagePlugin, ImageOps
Image.MAX_IMAGE_PIXELS = None
src_img = Image.open("7ba1a16b64cb74a285d0b8f0e5ea652d-2002-078-839.tif")
exif = src_img.getexif()
dst_img = ImageOps.exif_transpose(src_img).convert("RGB")
dst_img.save("test.jpg", quality=95, exif=exif)

Removing the tag allows the jpeg to be saved successfully. This seems to be at least related to the same tag as issue #5852.
