Bug ID: 499537
Summary: Three kwin and plasmashell kconf update programs
crashed when Plasma started
Classification: Plasma
Product: plasmashell
Version: 6.2.90
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: matt.fagn...@bell.net
Target Milestone: 1.0
SUMMARY
I booted the Fedora Rawhide live image
Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso in a QEMU/KVM VM in
GNOME Boxes in a Fedora 41 KDE installation. Three kwin and plasmashell kconf
update programs crashed when Plasma started:
/usr/lib64/kconf_update_bin/kwin-6.0-reset-active-mouse-screen,
/usr/lib64/kconf_update_bin/plasmashell-6.0-keep-custom-position-of-panels, and
/usr/lib64/kconf_update_bin/plasmashell-6.0-keep-default-floating-setting-for-plasma-5-panels.
The traces of the 3 crashes looked similar if not the same. The crashes were in
std::__atomic_base<QReadWriteLockPrivate*>::load which had a null this pointer
which might indicate a null pointer dereference. There was a null this pointer
down to QSystemLocaleData::readEnvironment in frame 8 at least
Core was generated by
`/usr/lib64/kconf_update_bin/kwin-6.0-reset-active-mouse-screen'.
Program terminated with signal SIGSEGV, Segmentation fault.

I reproduced these crashes on bare metal with the same image. This image had Qt
6.8.2. These crashes didn't happen in previous Fedora Rawhide KDE live images
with Qt 6.8.1. Since much of the traces were in Qt, there might be some problem
with Qt 6.8.2 and these programs. Fedora Rawhide was built with a GCC 15
development version which has a problem
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=116506 which resulted in crashes
of Discover https://bugs.kde.org/show_bug.cgi?id=499100 and plasmashell
https://bugs.kde.org/show_bug.cgi?id=499218
STEPS TO REPRODUCE
1. in a Fedora 41 KDE installation, download Fedora Rawhide KDE live image
Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso from
https://kojipkgs.fedoraproject.org//packages/Fedora-KDE-Desktop-Live/Rawhide/20250204.n.0/images/Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso
2. install GNOME Boxes if it isn't already with sudo dnf install gnome-boxes
3. Start GNOME Boxes
4. Boot Fedora-KDE-Desktop-Live-Rawhide-20250204.n.0.x86_64.iso in a QEMU/KVM
VM in GNOME Boxes with 3D acceleration enabled, 4 GB RAM, UEFI enabled.
OBSERVED RESULT
Three kwin and plasmashell kconf update programs crashed when Plasma started
EXPECTED RESULT
No crashes should've happened.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Rawhide/42
KDE Plasma Version: 6.2.90
KDE Frameworks Version: 6.10.0
Qt Version: 6.8.2
