-- Information about the crash:
This hung it and the shell, for < 2 s. Immediately, the shell closed, then
reinvoked, as if I'd executed `kquitapp6 plasmashell && plasmashell`.
About the warnings at the start of the trace, I've asked

That was all I was able to locate on the topic, so I've been unable to
remediate them. Even if I had been able to, this reproduces so
rarely/inconsistently that I doubt that I would have been able to generate a
new one.
The crash can be reproduced sometimes.
