English Applications

Hello,

I’m on snapshot VERSION_ID="20241226"
I have a strange problem with dolphin in super user mode:
I loaded dolphin from the application launcher and there were 4 tabs open pointing to different folders. I tried to open another folder in a new tab and dolphin crashed. In journalctl I have these messages :

I reopened dolphin in super user mode and the 4 tabs where still available , I removed 3 tabs and tried again to open a folder in a new tab with the same result: crash.

If I open dolphin as a normal user I can add new tabs without crash and if I select therein a folder and with shift select ==> Open folder with ==> “! File manager - super User mode” it loads Dolphin in super user mode asking for root password and open the folder in a new tab!

in journalctl the error message

Jan 01 10:26:43 hpprol2 systemd-coredump[434714]: Resource limits disable core dumping for process 434539 (dolphin).

seems strange because top gives me these info and I assume that I have enough ressources available

Any Idea where to look?

I presume you have dolphin-24.12.0-2.1.x86_64. Could you please try the former version, e.g., from here https://download.opensuse.org/history/20241220/tumbleweed/repo/oss/ to check whether the issue still exists?

3

I cannot reproduce it.

4

I installed version 24.12.0-1.1 for dolphin and dolphin-part but the same crash occurs when I try to open a folder or a device or a place in a new tab.

Regards
Philippe

Tried to reproduce your issue with TW20241226, but couldn’t. Bug report at https://bugzilla.opensuse.org?

6

I do not use Dolphin “as root”, thus I have no experience.
But you could check (as root in it’s home directory) if there is .cache/dolphin and remove it.

7

I removed
/root/.cache/doplhin/*
/root/.config/dolphinrc
/root/.config/ session/dolphin_dophin_dolphin

I needed to reconfigure dolphin (toolbar, icon size etc) but when I try to open a folder in a new tab I have still a crash

8

Does ‘kdesu dolphin’ from the CLI work?

It started happening a few weeks back, but I haven’t been bothered enough… still, if it’d help:

This is after running it with kdesu dolphin
(you’d have to manually modify the dump core limit with
sudo prlimit -c=10000000 -p <root dolphin's pid>)

Hello,

Yes it works if I load it via kdesu.

I tested also replacing in the org.kde.dolphinsu the dbus-launch by kdesu and then also dolphin in super user mode can open a folder in a new tab without crash.

Is there a problem with dbus-launch?

I see a forum discussion with a problem with dolphin in super user mode but it is not the same as mine
https://forums.opensuse.org/t/dolphin-not-open-in-super-user-mode/181151/39

Many thanks

I am unclear as to what the real culprit is and whether it is related, but could you please add your observation to 1234692 – Moval of dbus-launch to dbus-daemon prevents start of Dolphin super user mode. By the way, isn’t ‘Exec=dolphin’ in /usr/share/applications/org.kde.dolphinsu.desktop sufficient?

TLDR: So you already have: dbus-1-daemon installed?

The link to the thread you posted the user @hui states that the problem in that thread was caused by dbus-1-daemon missing on the system.

So to check you could:

zypper se dbus-1-daemon

If it is not marked as installed then:

sudo zypper in dbus-1-daemon

Done

Sorry? The current desktop file does not have any dbus-launch. Are you sure all your packages are up to date?

hello,

It was the file /home/philippe/.local/share/applications/org.kde.dolphinsu.desktop where philippe is my normal user.
I see that in /usr/share/applications/org.kde.dolphinsu.desktop there is still

[Desktop Entry]
Name=File Manager - Super User Mode
Exec=dbus-launch dolphin -qwindowtitle "%c" "%u"
Icon=system-file-manager

with last modified date = 2024-12-08 and I use zypper dup every time when I update my system.

Regards
Philippe

Dup in general does not change things in /home only system stuff. /home is personal settings only.

Ok I see that I had still dolphin-24.12.0-1.1 manually installed for testing.
I did a zypper dup and now i have in /usr/share/applications/org.kde.dolphinsu.desktop

Exec=/usr/bin/xdg-su -c dolphin

Setting this in my user settings for dolphin in super user mode works.

Many thanks
Philippe

And what prevented you from telling from the very beginning that you were using customized desktop file and showing your customization? Instead of wasting time of all users trying to reproduce your problem?
