SUMMARY Konsole is not able to close only the concerned split view. Instead, it asks Konsole to close the window and warns about split view left opened. Yes -> close Konsole No -> crash Konsole! Cancel -> crash Konsole! STEPS TO REPRODUCE 1. Open Konsole 2. Split view 3. Try to close one of the splitted view OBSERVED RESULT Konsole asks if we are sure to close Konsole because there are still opened splitted view. Yes -> close Konsole No -> crash Konsole! Cancel -> crash Konsole! EXPECTED RESULT Close the concerned splitted view without asking.

Reproducible on Neon Unstable Konsole 21.11.70 Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.22.80 KDE Frameworks Version: 5.85.0 Qt Version: 5.15.3 Kernel Version: 5.11.0-25-generic (64-bit) Graphics Platform: Wayland Processors: 2 × AMD A6-6400K APU with Radeon(tm) HD Graphics Memory: 7.7 GiB of RAM Graphics Processor: AMD CEDAR

@Julien: are you also using wayland? Unfortunately the backtrace is incomplete; please install the debuginfo packages (or whatever they're called in your distro) and provide the crash bt again.
@Ahmad no I'm using X11, it's just that I tested with wayland just to see what happens. You can see in my first post: Graphics Platform: X11 I will try to build with debug USE flag in my Gentoo as soon as possible.
So, unfortunately I didn't managed to get a better backtrace… but! I just applied the patch you have developed here: https://invent.kde.org/utilities/konsole/-/commit/4a3cab03f5d853f4dd48531979fc3fb57dde5e2e?merge_request_iid=458 And with this, everything works like a charm! Good job. :)
Thanks for the feedback.

When closing a session, don't close the whole window if there are splits When closing a session, we check if that is the last tab, and make the code close the whole window, but we also need to make sure it's the last view, i.e. no split views.

Is this fully fixed now, or is there more to do?
