Bug ID: 459127
Summary: Instant crash + crash handler also crashes
Product: systemsettings
Version: 5.25.5
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: 0voyl...@gmail.com
Target Milestone: ---
SUMMARY
I can not open any KDE program anymore without it crashing. Even the crash
handler crashes as soon as I press "Developer Information" or "Report Bug". The
signal I get is a Segmentation fault (11).
I've been trying to find what is causing this, but can not find a single clue
or way to fix it. Doing the backtrace stuff also does not seem to give many
results to help me fix it (or maybe it's obvious and I'm just not good at this
kind of stuff).
When I run coredumpctl gdb PID I get this:

***
STEPS TO REPRODUCE
1. Open any KDE application (systemsettings, kdenlive, ...)
OBSERVED RESULT
Instant crashes with a window saying that it crashed, which then results in
crashing itself when you press a button.
EXPECTED RESULT
To not crash when simply opening a program.
SOFTWARE/OS VERSIONS
Linux: Arch Linux lts 5.15.67-1-lts (Same problem happens on the linux (non
lts) kernel)
Qt Version: QT5 and QT6 installed
