ADDITIONAL INFORMATION
Comment 1 Nate Graham 2024-03-01 07:16:05 UTC 
Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols that we need to figure out exactly what's going wrong.

Could you please install debug symbols and attach a new symbolicated backtrace generated by using coredumpctl gdb in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.

Thanks again!

Comment 3 Nicolas Fella 2024-03-02 18:28:02 UTC 
Thanks. Are you using the synaptics input driver?
Comment 4 Nicolas Fella 2024-03-02 18:28:37 UTC 
*** Bug 482183 has been marked as a duplicate of this bug. ***
Comment 5 Nicolas 2024-03-02 21:17:30 UTC 
how can I check which driver is used. Also note that The following message was shown before the crash: 

systemsettings[28428]: kcm_mouse: Not able to select appropriate backend.

> Thanks. Are you using the synaptics input driver?

I got the same issue and yes I'm using the synaptics input driver which works just fine like a normal mouse on my system. The other things that might be related is thing like if I connect a USB mouse, the touchpad remain active (I did an upgrade from KDE5 to KDE6, so all previous settings should still apply but they don't because of the crash).  

[ebuild   R    ] x11-drivers/xf86-input-synaptics-1.9.2::gentoo

This issue also was present on plasma-desktop RC1 and RC2.
Comment 7 Nicolas 2024-03-04 07:39:43 UTC 
Uninstalling xserver-xorg-input-synaptics and installing xserver-xorg-input-libinput workarounds the crashes.
Comment 8 Francois C. 2024-03-04 22:43:17 UTC 
(In reply to Nicolas from comment #7)
> Uninstalling xserver-xorg-input-synaptics and installing
> xserver-xorg-input-libinput workarounds the crashes.

Same result w/o the synaptics drivers and

[ebuild   R    ] x11-drivers/xf86-input-libinput-1.4.0::gentoo

I may have a conflict now between x11-drivers/xf86-input-libinput & x11-drivers/xf86-input-evdev that doesn't hurt X11 but affect kcm_mouse.
Comment 9 Francois C. 2024-03-05 07:09:29 UTC 
> I may have a conflict now between x11-drivers/xf86-input-libinput &

I removed also x11-drivers/xf86-input-evdev, the issue is still there.

There is one thing that may be missing in the crash bug report. Before kcm_mouse crash, I receive a notification of a circular dependency on console. The following error appears twice.

qt.qml.typeresolution.cycle: Cyclic dependency detected between "qrc:/qt/qml/org/kde/desktop/private/TextFieldContextMenu.qml" and "qrc:/qt/qml/org/kde/desktop/MenuItem.qml"

Both files belongs to kde-frameworks/qqc2-desktop-style-6.0.0::gentoo package.

> systemsettings[28428]: kcm_mouse: Not able to select appropriate backend.

That's coming from this line in kcm_mouse:
https://invent.kde.org/plasma/plasma-desktop/-/blob/master/kcms/mouse/kcm/configplugin.cpp#L22

Which in turn is used by ConfigContainer, the thing that currently provides the system settings page:
https://invent.kde.org/plasma/plasma-desktop/-/blob/master/kcms/mouse/kcm/configcontainer.cpp#L27

When ConfigContainer::load() is called, it uses its ConfigPlugin without nullptr checks, crashing the KCM. It should probably have an early return in load(), save() and defaults(), closer to what kcm_touchpad is doing:

I think at the first place, the bug not able to detect a backend for mouse & touchpad also need to be fixed. It's a regression in KDE6; I never got this issue in KDE5 with the same hardware and same X11 drivers (xf86-input-evdev & xf86-input-synaptics for me).

That's weird, because the fix hasn't been merged yet. Maybe you got lucky with invalid memory access, or your distro picked up the patch on top of regular 6.0.1? Not sure honestly. Anyway, it's been approved so it will go into official 6.0.2.

The evdev and synaptics drivers were intentionally removed from the Mouse KCM, which is mentioned on https://community.kde.org/Plasma/Plasma_6#Removals with a link to the merge request and preceding discussion. That sucks for users that are still using those drivers, who now need to configure it via Xorg text file.

As someone who wasn't around for that discussion though, I have to say that the maintainability concerns were real. I'm now working on modernizing the Mouse and Touchpad KCMs for Plasma 6.1; with the extra evdev and synaptics backends it would have been absolutely daunting, now it's merely a lot of work.

kcms/mouse: Don't crash when no supported backend is found

If InputBackend::implementation() and ConfigPlugin::implementation()
can return a nullptr, we need to have null pointer checks where they
get used.

Also, remove some dead code without these checks to avoid confusion.

Not working for me and Jakob Petsovits is right, kcm_mouse will crash if no backend has been found. I compiled/updated all 6.0.1 yesterday and the latest version can't find a backend for my Logitech mouse and my Synaptics touchpad. I tried with xf86-input-libinput and (xf86-input-evdev + xf86-input-synaptics) without success.

Wait, xf86-input-libinput should work though. That backend is still in the code and used also on X11.

*used also on X11 _unless your distribution has compiled plasma-desktop without X11 support_

Jakob, you are right on that. For some stupid reason, Gentoo disabled X support by default. The bad new is, I recompiled plasma-desktop with X support and kcm_mouse still crash not able to find a backend with xf86-input-libinput. I didn't try with my last know configuration evdev & synaptics X11 drivers.

Forget my comment. When I tested, I was on remote desktop which crash kcm_mouse not finding mouse/touchpad because tigervnc don't provide any. You patch + QML change will fix the issue.

No, you did.

For the record: Of course in Gentoo X is enabled for desktop profiles, which you were expected to be using when running a desktop environment.
