GDB trace
my Plasma session was locked when strangely the laptop went into sleep mode.
When I have awaken it, and I unlocked the screen, I saw all opened applications
have disappeared.
I collected the GDB trace of kwin crash, see attachment.
A short resume of it is:
Core was generated by `/usr/bin/kwin_wayland --wayland-fd 5 --socket wayland-0
--xwayland-fd 6 --xwayl'.
Program terminated with signal SIGSEGV, Segmentation fault.
