-- Information about the crash:
I used Krunner to run `plasmashell --replace`. This worked, as in it replaced
the currently-running plasmashell, but Dr. Konqi also showed up to tell me
about a segfault in plasmashell. I couldn't get it to do it again, but maybe it
only happens when the session-invoked plasmashell is replaced? I will try again
after a reboot and update y'all.
The crash does not seem to be reproducible.
