Screenshot that demonstrates the problem

SUMMARY
KDE software doesn't detect remaining disk space properly.
Dolphin shows an empty bar in place of remaining disk space
Ark is unable to extract anything and thinks that there's no space
Good ol' `df -h` shows that there's 700 GB available on disk (visible in the screenshot)


STEPS TO REPRODUCE
Unfortunately, unknown. It just happend for me right now

OBSERVED RESULT
KDE software doesn't properly detect remaining space. Ark extraction fails, Dolphin doesn't show remaining space and shows an empty bar instead

EXPECTED RESULT
Remaining disk space is detected properly

I can reproduce this. I'm using a btrfs subvolume for home folder.
Dolphin is showing the following logs when trying to check disk space.

dolphin[8683]: kf.kio.widgets: Could not find mount point for QUrl("file:///home/user")
dolphin[9674]: kf.kio.widgets: Could not find mount point for QUrl("file:///home/user")

I think this issue is not quite resolved, as it still occurs on openSUSE Tumbleweed with Dolphin 24.05.2, built with QT 6.7.2, even though the fix for this issue landed in 6.7.

Then please comment on the Qt bug, not here. The issue is not in Dolphin.
