-- Information about the crash:
I'd merely left the OS idle for PT3M. (When I moved my mouse, some
notifications appeared, which were quickly replaced by one about Discover
crashing. I doubt that they were relevant.) This is the upstream counterpart to
https://bugzilla.redhat.com/show_bug.cgi?id=2374277#c14.
The crash can be reproduced sometimes.
