Description Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-06-26 20:57:12 UTC 
Description of problem:
Per https://bugzilla.redhat.com/show_bug.cgi?id=2374526#c1, "When I reinitialised from suspension via KScreenLocker, Plasma Shell was hung. It momentarily stopped being so, during which I attempted to invoke GNOME Abrt. I attempted to log out whilst it wwas hung again, but GA finally launched. After some time, it killed it, evidently as a last resort when log out has failed."

Plasma shell hung again. After `org.kde.Shutdown /Shutdown org.kde.Shutdown.logoutAndReboot`, GNOME Abrt appeared, indicating that the shell crashed.

Comment 14 Mr. Beedell, Roke Julian Lockhart (RJLB) 2025-07-21 23:05:03 UTC 
Almost immediately after experiencing https://crash-stats.mozilla.org/report/index/74277de6-f0c8-4fe4-bb6a-1f8230250721, I attempted to invoke `file:///usr/share/applications/org.freedesktop.GnomeAbrt.desktop` via the Icons-Only Task Manager. This caused `plasmashell` to hang, so I invoked the equivalent of `qdbus-qt6 org.kde.LogoutPrompt /LogoutPrompt org.kde.LogoutPrompt.promptLogout` from `krunner`'s relevant shell integration.

I'll attempt to report upstream when https://discuss.kde.org/t/can-a-desktop-session-action-like-logout-and-shutdown-be-cancelled/37436?u=rokejulianlockhart has been remediated.
