journald log drkonqi SIGABRT corefile messages

See also Bug 514326 (ksecretd crashed drkonqi and kded6)
Drkonqi generates a SIGABRT corefile after crashes of ksecretd.

It appears that the X11 display :0 was not accessible to drkonqi and kded6 at the time(s) when ksecretd had it's corefile dumped.

The drkonqi and kded6 log messages from the times of the SIGABRT coredumps below are given here.
The Kde desktop screen was locked by the user at that time; with the external display switched off.

The Kde user was already logged out, or may have been in the process of logging out of the desktop, at the times of the other instances of this problem.

However, shouldn't specifically in the case of the locked Kde desktop a X11 display :0 be available for applications?

If this is a security issue in connection with the crashed ksecretd, can drkonqi be made to safely recover it's operation?

What is the policy for drkonqi for the cases when the user is either logged out, or when the Kde screen is locked (for a longer timespan)? Would it make sense to have drkonqi generate some desktop Notifications for later use?

Bug 514326 (ksecretd crashed drkonqi and kded6)
Before this problem:
Installed all available software updates with zypper dup
openSUSE Tumbleweed 20260106

KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
Kernel Version: 6.18.3-1-default (64-bit)
Graphics Platform: X11
Processors: 22 × Intel® Core™ Ultra 7 155H
Memory: 128 GiB of RAM (125.1 GiB usable)
Graphics Processor: Intel® Arc
Manufacturer: ASUSTeK COMPUTER INC.
Product Name: NUC14RVH-B

Then:
Rebooted the host into Kde Plasma desktop.
Worked on the computer as usual.
Kept the computer running with the Kde screen locked.

Reproduce the problem maybe with:
Use the Kde Plasma desktop as usual.
Activate the Kde desktop Screen Locking with a configured keyboard shortcut.
With the Kde desktop locked, let the computer run for a longer timespan; if in doubt overnight.

Other information:
There was no installation of new software at the time of this problem.
The Kde Plasma desktop was found crashed after re-login into the (ok) screen-locked computer. The computer screen was completely black, with the exception of pre-existing Kde application windows. There was no coredump from plasmashell.

The computer has SELinux active, with "SELINUX=permissive".

As noted in the other issue, this is probably the main cause for the DrKonqi SIGABRT.

Comment 3 michaelk83 2026-01-13 09:56:47 UTC

A suggestion to the devs: if something crashes outside of an active GUI session (e.g. when it's locked), could the DrKonqi start up be delayed until the session is activated? At that point, DrKonqi could look back at unreported crash logs, and show the necessary dialogs retroactively.

That's not a bad suggestion, but it needs its own report. Please open a new bug report as "wishlist" so the developers can consider the feature request.

It was offered as a direct solution to this issue.
