Bug ID: 416937
Summary: Dolphin occasionally takes 1 minute to start
Product: dolphin
Version: 19.12.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: tagwer...@innerjoin.org
CC: kfm-de...@kde.org
Target Milestone: ---
Created attachment 125538
--> https://bugs.kde.org/attachment.cgi?id=125538&action=edit
ZIP of screen recording, strace showing delay, strace showing normal operation
SUMMARY:
At times Dolphin is very slow to start (and then to navigate). Whether
launched from a link or the command line, it takes about a minute to start
properly. The majority of the time it starts within a couple of seconds, then
for no discernable reason it takes 30 seconds for Dolphin to appear on screen
and another 25/30 seconds for the panel to be populated (see attached screen
recording). This behaviour persists for some minutes and then goes back to
normal. If you log out and back in again, the problem goes away.
STEPS TO REPRODUCE:
No fixed or repeatable way of reproducing this.
Tested in a KVM guest under a 'test' username with a small number of user
files. No mounts of other filesystems, local or remote. No tags defined. In
this configuration, actively trying to provoke the bug, it happens one or twice
a day.
OBSERVED RESULTS:
If watching the process list, when Dolphin is launched, /usr/bin/dolphin
runs. After 30 seconds Dolphin appears on screen and a set of files.so and
tags.so processes appear. Than after a further 25/30 seconds the contents of
the folder is displayed
Collect more information with strace:
strace -o trace -t -f /usr/bin/dolphin /home/test/Picture
shows sequences of ETIMEDOUT errors (with 5 second delays). The strace is
also attached (and a trace with normal operation)
Seems independent of baloo (or at least purging and reindexing does not
make a difference)

ADDITIONAL INFORMATION
In relation to https://bugs.kde.org/show_bug.cgi?id=409574; read up that
one while trying to work out what was happening here. No mention in this
instance of trying to open LC_SCRIPTS. Regional settings were left 'as is' as
en_US...
