dolphin 22.04.3-1
dolphin-plugins 22.04.3-1
ffmpegthumbs 22.04.3-1
Distro: Manjaro (Arch based)

Same issue here. I have FreeBSD running ZFS on slow SMR HDD drives (broken by
design) which causes very long syncing and write/read issues. The entire Samba
share becomes unmountable when thumbnailer hangs and kill -9 dolphin and plugin
process(es) just hangs forever. You have to boot the entire machine every time
to fix the issue. 

The way to fix this would be to add timeout and/or retry to the thumbnailer or
to the entire Dolphin preview plugin system which calls the preview plugins.

Adding caching to the thumbs to ~/.cache or something could also help somewhat
to decrease read count, but it would not fix the issue.
