            Bug ID: 452527
           Summary: Dolphin crashes after closing it by clicking the Close
                    Tab option in KCommandBar
           Product: dolphin
           Version: 21.12.3
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org

  Target Milestone: ---

Application: dolphin (21.12.3)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.17.1-arch1-1 x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I closed Dolphin using the Close Tab option in KCommandBar.
I got Dolphin crashed on both X11 and Wayland.

- Steps to reproduce:
1. Open Dolphin.
2. Launch KCommandBar by pressing Ctrl+Alt+I
3. Click on the 'Dolphin: Close Tab' option. (Dolphin won't crash by pressing
the key binding Ctrl+W)
After selecting that option in KCommandBar, Dolphin will actually crash instead
of just closing.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
