Bug ID: 413901
Summary: Konsole aborted when its Wayland connection broke
Product: ksysguard
Version: 5.16.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: matthew.fagn...@utoronto.ca
Target Milestone: ---
Application: ksysguard (5.16.5)
Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.8-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I was running Plasma 5.16.5 on Wayland in Fedora 31. I updated the system with
the updates-testing repo enabled using sudo dnf upgrade --refresh. The update
was taking longer than usual, and the system was slowing down. I started
ksysguard 5.16.5. ksysguard's title bar showed (Not Responding) and its colours
were faded. I tried to click on the CPU column title to sort by it. After about
a minute, ksysguard aborted with a message that the Wayland connection had
broken in the journal and trace.
ksysguard[3134]: The Wayland connection broke. Did the Wayland compositor die?
No other programs showed such a message about the Wayland connection breaking
in the journal. The update completed correctly after a few minutes. I saw a
similar abort of konsole with the same "The Wayland connection broke" message
three weeks ago https://bugs.kde.org/show_bug.cgi?id=413058
-- Backtrace:
Application: System Monitor (ksysguard), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
