dolphin (23.04.3) using Qt 5.15.10

I was running the test suite for gtk4 after building it from source, which involves creating and destroying a very large number of windows of various types. This concluded successfully. I then ran `sudo ninja install` to install the freshly built gtk4. This involved copying a large number of files.

As the install finished (I have no idea if it was related) Plasmashell crashed. When it automatically restarted, dolphin had closed and DrKonqi was open prompting me to submit this. So, I believe Plasmashell crashing triggered dolphin to crash.

dolphin (23.04.3) using Qt 5.15.10

Ran `killall plasmashell` in terminal, dolphin crashed at the same time. When I restarted plasmashell, DrKonqi appeared.

Comment 4 Oliver Hiorns 2023-09-03 18:52:14 UTC

I am still experiencing this issue, so I don't think it was a duplicate after all.

Comment 5 Christoph Cullmann 2023-09-03 21:19:35 UTC

It was a duplicate, but you are right, the fix seems not to be sufficient.
