-- Information about the crash:
xembedsniproxy crashed during lockscreen or after unlock screen.

The report says that Windowing System is X11 (I don’t know why), but I swear that I’m under Wayland during this session, here is my kinfo, launched via konsole during the very same session:
$ kinfo

Note: my plasmashell session run under wayland, but sddm run under X11.

The crash can be reproduced sometimes.
