Description Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-08-25 15:58:56 UTC 
Description of problem:
I had `cat /dev/random` open in a few terminals, which appeared to utterly hammer DBus, as https://bugzilla.redhat.com/show_bug.cgi?id=2390811#c0 demonstrates. Although it had periodically hung, when I closed it, it hung, then crashed. This may relate to https://bugs.kde.org/show_bug.cgi?id=506880#c9.
