Bug ID: 421170
Summary: plasmashell 5.18.5 on Wayland segmentation fault in
QVector<QQuickItemPrivate::ChangeListener>::indexOf
Product: plasmashell
Version: 5.18.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: matthew.fagn...@utoronto.ca
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.18.5)
Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.7.0-0.rc4.1.fc33.x86_64 x86_64
Windowing system: Wayland
Distribution: Fedora 33 (KDE Plasma Prerelease)
-- Information about the crash:
- What I was doing when the application crashed:
I booted a Fedora Rawhide KDE Plasma spin live image
Fedora-KDE-Live-x86_64-Rawhide-20200505.n.0.iso. In Plasma System Settings, I
shut off autologin, reduced the screen brightness, changed the compositor
rendering backend to OpenGL 3.1, and shut off the lock screen. I logged out. I
switched to a VT and ran sudo dnf upgrade --refresh -x kernel*. The update
included Plasma 5.18.5 and KF 5.70.0. I installed kwin-wayland,
plasma-workspace-wayland, xorg-x11-drv-amdgpu, and their dependencies. I logged
out of the VT and switched to sddm. I logged into Plasma on Wayland. I added
the firefox on wayland icon from the menu to the desktop. I sorted the icons
into columns using the right-click menu on the desktop.
plasmashell crashed with a segmentation fault in
QVector<QQuickItemPrivate::ChangeListener>::indexOf at
/usr/include/qt5/QtCore/qvector.h:1008 in qt 5.14.2. I saw this crash twice
before on the previous boot when clicking on a Thundebird on Wayland icon on
the desktop in Plasma 5.18.5 on Wayland. I hadn't seen plasmashell crashes with
this traces with Plasma 5.18.4.1 and KF 5.69.0 and earlier.
- Unusual behavior I noticed:
The desktop went black. plasmashell restarted automatically.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
