           Summary: Kate sometimes crashes when rejecting an
                    auto-suggestion; typing with Mallit Keyboard

Windowing System: Wayland
Drkonqi Version: 5.22.4
Distribution: Fedora 34 (KDE Plasma)

-- Information about the crash:
- What I was doing when the application crashed:
 * Typing "case QEvent::Gesture:" in
konsole/src/terminalDisplay/TerminalDisplay.cpp::event
 * Typing “QEv:” in the same file (while auto-suggest shows “QEvent” as top
result.

- Additional Information
 * Auto-suggest was showing “GestureType” as the top suggestion when “:” was
pressed.
 * Typing “case QEvent::GestureB: ”, then editing to “case QEvent::Gesture:”
does not trigger the issue.


- Custom settings of the application:
 * Touchscreen device on Wayland/Plasma
 * Using maliit keyboard
  * Mallit-keyboard auto-suggest, auto-complete, auto-caps all disabled

The crash can be reproduced every time.

-- Backtrace:
