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 was 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.

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.

Comment 19 Fedora Release Engineering 2026-05-06 13:22:45 UTC
This message is a reminder that Fedora Linux 42 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 42 on 2026-05-13.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained. At that time this bug will be closed as EOL if it remains open with a
'version' of '42'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 42 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.
