Bug 431827

Summary: Konsole crashes if issuing CTLR+d if input is copied to other tabs
Product: [Applications] konsole Reporter: Michael M <redeamer>
Component: generalAssignee: Konsole Developer <konsole-devel>
Status: RESOLVED FIXED    
Severity: crash CC: bugseforuns, greatsport1, jkt

Version: 20.12.1

Platform: Debian unstable   
OS: Linux   
Latest Commit: https://invent.kde.org/utilities/konsole/commit/fc7850c3e396400e82ad99bacaf9e4f825c083a9 Version Fixed In: 20.12.2
Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description Michael M 2021-01-19 20:50:36 UTC 
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

Committed on 21/01/2021 at 18:20.

Fix crash exiting all tabs at the same time

It was emitting a signal with a nullptr and updating an icon of a
nullptr as the TerminalDisplay was already deleted.
