            Bug ID: 431827
           Summary: Konsole crashes if issuing CTLR+d if input is copied
                    to other tabs
           Product: konsole
           Version: 20.12.1
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: redeamer at gmx.net
  Target Milestone: ---

Application: konsole (20.12.1)

Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.0-1-amd64 x86_64
Windowing system: X11
Distribution: Debian GNU/Linux bullseye/sid

-- Information about the crash:
- What I was doing when the application crashed:

- Open konsole
- Open four (works with two too, but less reliable) tabs
- Go back to first tab -> select 'Edit -> Copy Input To -> All Tabs in Current
window'
- Switch through all tabs again
- Go back to first tab -> type 'ls -l'
- Switch through all tabs again
- Go back to first tab -> press 'CTRL + d' to exit -> CRASH

It sounds pretty much like a duplicate from 405158, but the fixed lines are
present in the source debian unstable uses to compile currently
(konsole-20.12.1). So therefore creating a new issue.

The crash can be reproduced sometimes.

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