            Bug ID: 411561
           Summary: Konsole segfaults when sending `exit` to multiple tabs
           Product: konsole
           Version: 19.08.0
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: isalgueiro at gmail.com
  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
Distribution: KDE neon User Edition 5.16

-- 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.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
