Application: kate (18.08.0)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-5-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:
I can reproduce by opening Kate fresh, clicking in the embedded terminal pane, and then pasting using Ctrl-Shift-v.

I'm not sure if I had to set the keyboard shortcut for paste manually for the shortcut. Pasting using the right-click context menu in the terminal pane works as expected.

The crash can be reproduced every time.

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