I would reference also the bug #454722 - Dolphin becomes frozen if nfs shares
declared in fstab are not available - previously the mount point was just
showing empty. Currently reproduced with Dolphin 23.08.2.

I have observed the same but it is not limited to NFS shares.
For me file dialogs get slow when I have a "noauto" mount entry in /etc/fstab
AND that device is not available.
In my case that is the entry for an external USB-HD:

LABEL=ExtBackup   /media/ebackup  ext4defaults,lazytime,noauto0   2

If I comment out that line, dolphin (and other file dialogs) are fast and
responsive.
If the line is active AND the ExtHD is not connected, then browsing dirs is
extremely sluggish (upto few seconds delays).
If the ExtHD is connected but not mounted, then also everything behaves
normally.

I'm using Kubuntu 21.10 with Plasma 5.22.5 and Frameworks 5.86.0.
Kubuntu 21.04 did not had this problem yet.

Same here, except things are worse since KDE Gear 21.08. Every process in need
to list files is very very slow (`ls` in Konsole, Gwenview, Okular, …), Dolphin
window is freezed and must be killed (even if launched on /opt url for
example).

My NFS automounted share is in my home folder. Here's Dolphin BT, but dbg
symbols are not yet availables on Debian.

Sorry for my lack of experience with this, how can I get a backtrace? Dolphin
is not crashing, just hanging.

I bet this is the free space bar in places panel trying to query available
space. This patch [1] should alleviate this but it would be great if you could
get a backtrace when this happens. Re-assigning to KIO as the file dialog comes
from there.
