Comment 5 Martyn Lewis 2023-08-16 19:22:46 UTC 
Same problem here, two files in particular - one jpg and one png. I have tried with various other png and jpgs and no problem with them.

New crash information added by DrKonqi

gwenview (23.08.1) using Qt 5.15.10

I was creating some images using Stable Diffusion and noticed images produced when I selected the option to embed the prompt settings to produce the image in the png file would cause gwenview to crash. Images where I chose to generate a separate .json file instead were unaffected.

I tested the exif2 issue linked in https://bugs.kde.org/show_bug.cgi?id=471029#c4 and following the brief test shows a similar result: 

```
exiv2 --Print xkycvt origami_style_blue_river_flowing_through_wooden_va_CRCGSAZ0.png
Uncaught exception: Overflow in Exiv2::DataBuf::c_data
```

Comment 8 A Linux User 2025-08-19 17:18:31 UTC 
Is this still an issue?

I can no longer reproduce it, so I think it has been resolved.
