Bug 451808

Application: kate (20.04.2)

Qt Version: 5.12.7
Frameworks Version: 5.76.0
Operating System: Linux 5.3.18-150300.59.54-default x86_64
Windowing system: Wayland
Distribution: "openSUSE Leap 15.3"

-- Information about the crash:
- What I was doing when the application crashed:
Having an open/saved file I opened a second tab/file in the same window then closed the first tab without making any changes to either file. At this point Kate crashed. This has happened more than once.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kate (kate), signal: Aborted
