Bug ID: 396855
Summary: KDE System Configuration: Selecting SDDM in frequently
used configuration modules
Product: systemsettings
Version: 5.13.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: frede...@virot.fr
Target Milestone: ---
Application: systemsettings5 (5.13.3)
Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.17.9-1-ARCH x86_64
Distribution (Platform): Archlinux Packages
-- Information about the crash:
I opened the systemsettings5 application from the "K" menu. Then I selected
"Login Screen (SDDM)" from the "Frequently used:" pane.
And the application immediately crashed.
I restarted right after and could do exactly the same thing without crash.
Multiple times.
This behaviour occured on a freshly installed ArchLinux system, right after the
machine was rebooted followng a software update in which the kernel was
updated.
output of uname -a after crash:
Linux lerins 4.17.9-1-ARCH #1 SMP PREEMPT Sun Jul 22 20:23:36 UTC 2018 x86_64
GNU/Linux
The machine had been updated on a daily basis before this issue occured and
rebooted right after the kernel update. After the reboot, a regular user
session was entered using KDE as DM and systemsettings5 was among the first
applications to be used.
-- Backtrace:
Application: Configuration du système (systemsettings5), signal: Segmentation
fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
