Bug ID: 462841
Summary: System Monitor crashed in QEvent::isAccepted when
killing a process
Classification: Plasma
Product: plasma-systemmonitor
Version: 5.26.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]

Target Milestone: ---
Application: plasma-systemmonitor (5.26.4)
Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.12-300.fc37.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.26.4 [KCrashBackend]
-- Information about the crash:
I was using Plasma 5.26.4 on Wayland in a Fedora 37 KDE Plasma installation.
The program aide ran as root as a cron job. I started System Settings and
selected Processes. I had previously selected Show: All Processes. I
right-clicked on the aide process and selected Send Signal > Kill. The Plasma
polkit dialog appeared, and I entered the password and pressed OK. System
Settings crashed in QEvent::isAccepted at
/usr/include/qt5/QtCore/qcoreevent.h:305 from Qt 5.15.7. I haven't seen this
type of crash before.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: System Monitor (plasma-systemmonitor), signal: Segmentation fault
