SUMMARY Not clear how to reproduce it, but plasmashell has been crashing randomly for some time for me. Sometimes is right after clicking on the launcher icon, but sometimes is without having interacted explicitly. Not huge impact as plasmashell gets automatically restarted and I can keep working. I can see the following output from `journalctl --user`: ``` nov 29 16:35:48 apinovo systemd-coredump[14214]: [🡕] Process 7178 (plasmashell) of user 1004 dumped core.
