Bug 477224

Application: kate (23.08.1)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.5.4-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
I accidentally pressed the right and the left mouse buttons at the same time over the text editor area. Kate immediately crashed.

I think I pressed the right one first. I don't know whether the mouse moved slightly over the context menu in the meantime (where the first action would be Cut), nor if anything was selected. Pressing both of them at the same time is NOT configured to emulate middle click. It's a regular mouse (not touchpad), and the system is X11.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
