Hey, this may be a bit of a long shot, but as kioslave5 started started crashing for me today and I’m also on Kubuntu 24.04…
I checked my apt history and noticed that libexiv was upgraded this morning:
Start-Date: 2026-03-18 10:11:28
Commandline: /usr/bin/unattended-upgrade
Upgrade: libexiv2-27:amd64 (0.27.6-1build1, 0.27.6-1ubuntu0.1)
End-Date: 2026-03-18 10:11:29
After manually downgrading to version 0.27.6-1build1 of libexiv2-27 and rebooting (not sure if that’s required), Dolphin and Gwenview are working again without any kioslave5 crashes:
sudo apt install libexiv2-27=0.27.6-1build1
Hope it helps & good luck if it doesn’t!
