Application: kate (22.03.70)

Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.11.0-40-generic x86_64
Windowing System: Wayland
Distribution: KDE neon Unstable Edition
DrKonqi: 5.24.80 [CoredumpBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I was typing and Kate crashed at some point. Possibly the crash was triggered by the popup that suggests previously typed words.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kate (kate), signal: Aborted
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
