I have some files with .jpg extensions that are actually HEIF files. (I suspect it's the Android app for Instagram generating them on my phone, but haven't followed up.) Trying to process them with my normal processing script causes exiftool.process_file() to crash.
Here's a simplified version of the code causing the crash:
import exifread
with open("""IMG_20240322_014811_458.jpg""", 'rb') as f:
tags = exifread.process_file(f, details=False)
Here's a stack trace showing what's happening:
Traceback (most recent call last):
File "/usr/lib/python3.8/code.py", line 90, in runcode

item_id = meta.subs['iinf'].exif_infe.item_id
AttributeError: 'NoneType' object has no attribute 'item_id'
It looks like heic.find_exif() is returning None, but later code isn't checking for that possibility.
And I'm attaching a copy of a file that causes the crash:
