Dear Maintainer,
I curently started to use debian unstable and it was fine with plasma for some days. Then i did an apt upgrade and observed this bug. It is now impossible to use plasma on wayland. I have provided the logs i think are relevnat. I have tested this on a new user without any personal configs and the problem still remaines. Currenty I can use the system with X11.


Xwayland crashes frequently on my system with the error message indicating a core dump.

Steps to Reproduce:

    Start the system (SDDM) and log in.
    Every time i use wayland and login.
    Observe the crash and core dump.

Expected Results:

	Xwayland should run without crashing.

Actual Results:

	Xwayland crashes and generates a core dump.
