Comment 1 Alex 2021-08-22 02:19:51 UTC 
This crash is occurring frequently for me on Dolphin 21.08.0 on Fedora 34 Wayland session.
Comment 2 Nate Graham 2021-08-22 16:09:09 UTC 
Can confirm. Moving to Konsole as I believe there were some relevant changes to the KPart which could have caused this.

Git commit 2684bc7fa5ac0b740b3e8661c3a0ae0136fde0a7 by Ahmad Samir.
Committed on 22/08/2021 at 18:10.

Only emit empty() in SessionFinished() when in TabbedNavigation mode

empty() is emitted so that MainWindow calls close() and we get rid of the
colours-flashing bug when closing the last session/tab in a window, see
commit bbec72250d080. However all that isn't relevant when we are in
konsole Part mode, where there are no tabs or MainWindows.

This fixes a crash in Dolphin when closing its window while the embedded
Konsole Part is open. The crash would happen as calling
ViewContainer::currentTabViewCount() would end up in the ViewSplitter code
path, which is no-op in Konsole Part.

To test:
- Open dolphin, make sure the terminal panel isn't open to begin with
- open the terminal panel
- close the dolphin window while the terminal panel is open
FIXED-IN: 21.08.1

New crash information added by DrKonqi

dolphin (21.08.0) using Qt 5.15.2

- What I was doing when the application crashed:
Pressed F4 and then clicked the red close button with my mouse and it said it crashed after I took a screenshot

Yep, this is the same crash. The fix is shipped with 21.08.1 which should be available soon (depending on your distro)

It's probably fixed on Fedora 34 in 21.08.1 but in 21.08.0 it also crashes for me when terminal is hidden:

New crash information added by DrKonqi

kdevelop (5.6.2) using Qt 5.15.2

- What I was doing when the application crashed:

I was closing the KDEvelop application regularly over its menu point. Its reproducable every single time.
I understand, this was closed some time ago, but it seems as if there are some remnants somehere.
