           Summary: Konsole crashes when closing tabs
           Product: konsole
           Version: 20.04.1
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: mrdoctorwho at gmail.com
  Target Milestone: ---

Application: konsole (20.04.1)

Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.7.7-200.fc32.x86_64 x86_64
Windowing system: X11
Distribution: "Fedora release 32 (Thirty Two)"

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

So I had several tabs open on Konsole. Some tabs had programs running in them.
Sometimes when I close tabs with Ctrl+Shift+W or switch b/w them with
Shift+arrow key it just crashes and brings all processes with it.

The crash can be reproduced sometimes.

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