Bug 460593

Application: akonadiserver (5.21.1 (22.08.1))

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.15.0-50-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - 5.26
DrKonqi: 5.26.0 [KCrashBackend]

-- Information about the crash:
It happens randomnly some time after logging into plasma. Trying to switch to another program on plasma panel (icons only task list), either akonadi and/or plasmashell crashes.
It is related to bug nr 460575. I added it here because maybe the it has additional information.

The reporter is unsure if this crash is reproducible.

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