Bug 456509

Application: akonadiserver (5.20.1 (22.04.1))

Qt Version: 5.15.3
Frameworks Version: 5.94.0
Operating System: Linux 5.18.10-200.fc36.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 36 (KDE Plasma)
DrKonqi: 5.25.2 [KCrashBackend]

-- Information about the crash:
So I was editing something in LibreOffice writer, sometimes changing names of files in dolphin while watching Jimmy Dore on Youtube via Firefox. Then all the applications got ripped away.

This already happened a bit earlier today when I move the mouse to the top right corner of the screen. Wham! All the applications are gone.

This never happened before a "dnf update" I did "this morning" of 2022-07-09, so it has probably something to do with that.

Unfortunately I do not know which packages those were. The "dnf.log" in /var/log is not informative enough and my script to track package updates is currently out of commission. Just the right time.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
