Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: konsole-de...@kde.org

Target Milestone: ---
Application: konsole (19.08.0)
Qt Version: 5.12.3
Frameworks Version: 5.61.0
Operating System: Linux 5.0.0-27-generic x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I had a konsole window with 7 tabs oppened: 6 ssh sessions and a local shell.
In one of the ssh sessions tab I selected Edit / Copy input to / All tabs in
current window and executed `exit`. Konsole crashed with attached backtrace.
The crash can be reproduced every time.
