SUMMARY

I booted the Fedora Rawhide/40 KDE Plasma live image Fedora-KDE-Live-x86_64-Rawhide-20231204.n.0.iso on bare metal. I started Konsole in Plasma 5.90.0 on Wayland. I ran some Fedora kernel tests in Konsole. I quickly moved the cursor over the Konsole icon in the task manager to the icons to its left (Firefox, Dolphin, Discover, System Settings). plasmashell crashed when I did that and the panel disappeared and reappeared automatically a few seconds later. drkonqi appeared. I selected Developer information, installed debuginfo rpms for qt6-qtbase(-gui) glibc glib2, and created a trace. I tried to report through bugs.kde.org through drkonqi, but drkonqi crashed at the point that a list of possible duplicate reports was shown. The trace from coredumpctl info is as follows. The core dump was removed probably due to space limitations from the drkonqi crash.
The crash was a segmentation fault involving QWaitCondition::wait in qt6-qtbase 6.6.1.

                ELF object binary architecture: AMD x86-64

I saw this type of plasmashell crash again in the same session by hovering over the task manager icons with Firefox, Konsole, System Monitor open in a similar way. The core dump wasn't saved due to space limitations and drkonqi didn't appear. The crash only happened sometimes.

STEPS TO REPRODUCE
1. boot the Fedora Rawhide/40 KDE Plasma live image Fedora-KDE-Live-x86_64-Rawhide-20231204.n.0.iso from https://koji.fedoraproject.org/koji/buildinfo?buildID=2327615 on bare metal. 
2. start Konsole in Plasma 5.90.0 on Wayland. 
3. quickly move the cursor over the Konsole icon in the task manager to the icons to its left (Firefox, Dolphin, Discover, System Settings) back and forth until the crash happens.

OBSERVED RESULT
plasmashell crashed in QWaitCondition::wait when hovering over task manager icons

EXPECTED RESULT
plasmashell shouldn't have crashed

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Rawhide/40
(available in About System)
KDE Plasma Version: 5.90.0
KDE Frameworks Version: 5.246.0
Qt Version: 6.6.1

ADDITIONAL INFORMATION

The trace was similar to that of https://bugs.kde.org/show_bug.cgi?id=472412 That report was closed with the instruction to make a new report if it still happened. https://bugs.kde.org/show_bug.cgi?id=472412#c2

Comment 1 Matt Fagnani 2023-12-04 22:29:52 UTC

I reproduced the crash by moving the cursor quickly between the Dolphin and Konsole icons which were both running. Here is the trace from coredumpctl gdb.

Core was generated by `/usr/bin/plasmashell --no-respawn'.

Comment 2 Nate Graham 2023-12-05 17:23:44 UTC

Does the issue reproduce if you uncheck "Show small preview windows when hovering over Tasks" in the Task Manager widget's settings window and then do the same thing to cause the crash to happen?

I unchecked "Show small preview windows when hovering over Tasks" in the Task Manager widget's settings window. I tried to reproduce the crash as in comment 1 for several minutes, but plasmashell didn't crash. The 5 crashes like this in Plasma 5.90.0 took from 1 second to 2 minutes to happen, so the problem might not happen with the preview windows disabled. I checked "Show small preview windows when hovering over Tasks" in the Task Manager widget's settings window. I reproduced the crash after about 1 minute of moving the cursor as before. I think that the problem is actually in thread 73 instead of thread 1 as in the trace I put in comment. drkonqi focused on thread 1, but it was just waiting/polling. Both thread 73 and thread 1 had [KCrash Handler] at the top in drkonqi. Using coredumpctl gdb, the trace of thread 73 was the following.

QtWaylandClient::QWaylandWindow::createDecoration in frame 7 of thread 73 had mShellSurface=0x0, so !mShellSurface->wantsDecorations() might've been a null pointer dereference at /usr/src/debug/qt6-qtwayland-6.6.1-1.fc40.x86_64/src/client/qwaylandwindow.cpp:1034. This problem might involve a race condition in which the Wayland surface of the window previews was occasionally freed then used.

Valgrind log from trying to reproduce plasmashell crash by hovering over task manager icons

I saw plasmashell crash with this type of trace in Plasma 5.90.0 when I disabled WiFi in the Plasma NetworkManager applet then clicked off of the applet to close it. This crash didn't usually happen when doing so.

I ran plasmashell under valgrind and reproduced the crash as before. The error The Wayland connection broke. Did the Wayland compositor die? was shown in Konsole so the crash might've been due to that different reason. The window previews for konsole and other running programs weren't shown when run under valgrind, but the popups with just their names were shown. There were many invalid reads which looked to be buffer overreads. The ones involving KSvg::SvgPrivate::createRenderer might be more likely to be involved with the window preview popups. I'm attaching the valgrind log.
