Bug ID: 513325
Summary: (regression) dolphin won't cache thumbnails for files
from LUKS container different from home folder
Classification: Applications
Product: dolphin
Version First 25.08.3
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Target Milestone: ---
SUMMARY
My disk setup: a single NVME drive with several logical volumes created by LVM,
each with their own LUKS container. They can be unlocked as needed, similar use
case to vaults or gocrypfts etc.
~/home is on a specific volume (e.g. xfs partition on an unlocked
/dev/mapper/luks-vg-home)
~/home/thing may be a different volume (e.g. xfs partition on
/dev/mapper/luks-vg-thing)
The only thumbnails that end up in ~/.cache/thumbnails are for files on the
same filesystem as ~/home. In the above example, any thumbnails in ~/home/thing
are regenerated every time.
I believe this changed in the last couple months, and before that it actually
did cache everything as expected.
STEPS TO REPRODUCE
1. Mount $HOME from xfs filesystem on LUKS container A
2. Mount some other $HOME/thing from xfs filesystem on LUKS container B
3. Browse files with Dolphin
OBSERVED RESULT
- Dolphin caches thumbnails for files from any encrypted filesystem
EXPECTED RESULT
- Dolphin caches thumbnails only for files in the encrypted filesystem that
$HOME is on
