crash log for journalctl
SUMMARY
KWin seg fault after running for many days without user input
STEPS TO REPRODUCE
1. Start Kwin with tty (`/usr/lib/plasma-dbus-run-session-if-needed
/usr/bin/startplasma-wayland`)
2. wait many days probably over a week
3. hope crash is reproducible
OBSERVED RESULT
Seg fault is logged in journalctl, but kwin restarts since plasmashell did not
crash
EXPECTED RESULT
no crash
SOFTWARE/OS VERSIONS
Operating System: Arch Linux

Qt Version: 6.7.1
Kernel Version: 6.9.6-zen1-1-zen (64-bit)
Graphics Platform: Wayland

ADDITIONAL INFORMATION
Sorry in advance about the missing debug symbols in the stack trace. However,
there does seem to be the C++ mangled names for Qt, and that might be enough to
go on when using a demangler like https://demangler.com/. There I was able to
get the source of the seg fault being in
`QCoreApplication::notifyInternal2(QObject*, QEvent*)` where the core
application is KWin.
