Description Roke Julian Lockhart Beedell 2025-11-23 21:58:49 UTC

Application: plasmashell (6.5.3)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.20.0
Operating System: Linux 6.17.8-300.fc43.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 43 (KDE Plasma Desktop Edition)"
DrKonqi: 6.5.3 [CoredumpBackend]

-- Information about the crash:
After invoking `sudo dnf5 upgrade --refresh --offline && sudo dnf5 offline reboot`, `plasmashell` repeatedly crashed.

I've yet to submit another crash log to demonstrate this. I've not been able to preserve any more crashes, because a reproduction of what https://bugzilla.redhat.com/show_bug.cgi?id=2378681#c33 describes (an OOM) destroyed one of Dr. Konqi's instances.

The crash can be reproduced sometimes.

Created attachment 187103 [details]
New crash information added by DrKonqi

DrKonqi auto-attaching complete backtrace.

Comment 2 Roke Julian Lockhart Beedell 2025-11-23 22:01:00 UTC

I've submitted the other trace to https://bugs.kde.org/show_bug.cgi?id=512533. In retrospect, after restarting PlasmaShell, it now endlessly crashes and reinitialises, so this *is* always reproducible.

Comment 3 Roke Julian Lockhart Beedell 2025-11-23 22:07:31 UTC

Reported downstream, at https://bugzilla.redhat.com/show_bug.cgi?id=2416610#c16.
