SUMMARY System Monitor 5.21.2 segmentation faulted in QWidget::internalWinId() at kernel/qwidget.h:222 in qt5-qtbase-5.15.2-13.fc34.x86_64 when terminating processes running as root. These crashes happened 4 of 4 times when running Plasma 5.21.2 on Wayland in a Fedora 34 KDE Plasma installation. I first noticed this crash after I stopped a backup with backintime and closed it. I saw rsync processes running as root still running in System Monitor, and I tried to terminate one rsync process. The second such crash happened when I tried to terminate the autostarted process /usr/bin/python3 -Es /usr/share/backintime/qt/serviceHelper.py from backintime. The trace below was from when I tried to terminate abrt-dump-journal-xorg which was running as root from the Processes screen by right clicking on abrt-dump-journal-xorg, selected Send Signal > Terminate, then End in the End Process box. The traces of the first 3 crashes looked the same. The crash happened before I guess that the KDE PolicyKit program would've appeared to prompt for a password.

STEPS TO REPRODUCE 1. Boot a Fedora 34 KDE Plasma installation updated to 2021-3-6 with updates-testing enabled 2. Log in to Plasma 5.21.2 on Wayland 3. Install plasma-systemmonitor if it isn't already with sudo dnf install plasma-systemmonitor 4. Start system monitor 5. Select the Processes screen 6. Select Show: All processes 7. right click on abrt-dump-journal-xorg 8. select Send Signal > Terminate 9. select End in the End Process box. OBSERVED RESULT System Monitor segmentation faulted in QWidget::internalWinId() when terminating processes running as root EXPECTED RESULT System Monitor would allow one to enter a password to authenticate then terminate the process without crashing SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 34 (available in About System) KDE Plasma Version: 5.21.2 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION drkonqi crashed twice when I was entering a description of what happened before the crashes in the "Information about the crash" box in a way like described at https://bugzilla.redhat.com/show_bug.cgi?id=1930946
I ran gdb plasma-systemmonitor and terminated abrt-dump-journal-xorg as I described. The segmentation fault was shown in QWidget::effectiveWinId which was frame 1 in the original trace. The polkit and kauth functions in kf5-kauth-5.79.0-2.fc34 in frames 1 and 2 might indicate that the KDE PolicyKit agent was in the process of starting when the crash happened.
