Gwenview backtrace

SUMMARY
After updating to libexiv2-27, gwenview now crashes when trying to load an image.  Gwenview can be run directly, as long as the root directory doesn't contain images.  After navigating to a folder with images, and once thumbnails start to be generated, it crashes.  I have a folder with 3 PNGs in it (scanned from my scanner) all between 18-30 MB each.  I have also tried to open small jpg files (under 100 KB) and it crashes instantly.

At first I wasn't sure that libexiv was the issue.  But I have another Kubuntu laptop with the same version of Gwenview and everything worked fine.  On this other laptop, an update for libexiv was available.  I did the update, and didn't even have to restart.  My next run of Gwenview crashed exactly the same as my first laptop.


STEPS TO REPRODUCE
1. start with Gwenview v23.08.5
2. update libexiv to 2.27
3. open any image file


OBSERVED RESULT
It crashes for me every time.  I've opened small jpg files (under 100 KB) and large png files (over 30 MB) and it crashes for all of them now.


EXPECTED RESULT
Image files should open normally, and thumbnail generation shouldn't crash gwenview.
