Definitively, forget the Snap 8.2.0 version which is outdated and use the Linux AppImage bundle instead that we provide. 

I recommend the 9.1.0 pre-release which include bug-fix only compared to the last 9.0.0 just released few weeks ago.

Comment 3 dev.schroeder.soft 2026-03-18 16:48:40 UTC

Switching to AppImage worked.

May try EXIF lib downgrade listed in 517733 to fix other issues until that lib updated.

I do it! Downgrade the libexiv2 and Showfoto/Digicam and Gwenview work again!
I will Hold in Synaptic the pack libexiv2 to the build version Until the New version with Fix comming out!
Using Appimage is a alternative soluttion But with this Bug I have many problems in Dolphin and other programs, i will not Keep using the Bug Version of libexiv2   0.27.6-1ubuntu0.1 but the build version that works fine until new updates!
Thanks for all!
