I found one file with this command:
/home/thierry/.config/gwenviewrc
Deleted it
New try: same result,crash.

Note: Is there others who use 4K monitor like me to test if that have influence?

If the problem is related to libexiv and it doesn't affect everyone, then it could be related to the input. Try starting gwenview on a set of images other than the default ones it tries to load at startup, e.g. "gwenview /tmp", so it attempts to load different (probably none, if given /tmp) images.

Assigning to Nicolas who implemented the latest security fixes.
Please reassign back to all packagers if you'd prefer not to handle this bug.

Theirry, if you can figure out which one it is, please see if it's suitable
for sharing.

I continued my research. It seems that the snapshots made with my Lumix GX80 and GX9 caused the crash. You will find in the link below an example file
https://www.cjoint.com/data/KIgghlOa8Ic_-1000094.jpg

I'm able to reproduce a crash with the command "exiv2 -pa pr  KIgghlOa8Ic_-1000094.jpg" so it looks like a libexiv2 regression.

Confirmed fixed for that image with the updated exiv package and still working
with my Pictures directory. Validating the update.

Working for me, too, also on mga8 x86_64.

It works fine now for me, I think this update validated.
