Bug 442147

Application: akonadiserver (5.18.1 (21.08.1))

Qt Version: 5.15.3
Frameworks Version: 5.85.0
Operating System: Linux 5.11.0-27-generic x86_64
Windowing System: Wayland
Drkonqi Version: 5.22.5
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
- What I was doing when the application crashed:

Writing some code in IntelliJ.

- Custom settings of the application:

This only happens once in awhile in Wayland, and, I *think* when IntelliJ tries to open a dialog window.

The reporter is unsure if this crash is reproducible.

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