kded5/kdeinit crashs when editing libinput touchpad settings

After I upgrade to kde 5.16, I found than everytime I edit my libinput touchpad settings, the kded5 or kdeinit will crash, and makes the 3rd-party app's tray icon disappears.

Restart plasmashell will recover it.

Here's the log:

Application: kdeinit5 (kdeinit5), signal: Segmentation fault

Re: kded5/kdeinit crashs when editing libinput touchpad settings

everytime I edit my libinput touchpad settings

What program/command/kde menuitem are you using to do that ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Re: kded5/kdeinit crashs when editing libinput touchpad settings

Okay,

I had the same issue although in my case, it usually crashed right after login. After installing xf86-input-synaptics it doesn't seem to crash anymore.
I know xf86-input-synaptics is no longer updated, but I had issues with the touchpad not being re-enabled after my bluetooth mouse disconnected anyway.

Re: kded5/kdeinit crashs when editing libinput touchpad settings

Probably it's something related with Qt5.12 because I have Qt5.13rc2 and this issue doesn't occur.

Re: kded5/kdeinit crashs when editing libinput touchpad settings

I can confirm my issue were resolved in Plasma 5.16.2 using libinput. I uninstalled xf86-input-synaptics.
