Description Oded Arbel 2021-06-06 08:47:47 UTC 
I'm using Neon developer edition with DBus integration turned on.

SUMMARY
Plasma crahes when opening the window operations menu and selecting "Desktop" -> "New Desktop".

STEPS TO REPRODUCE
1. Start a kwin wayland session.
2. Start an application
3. Open the window operations menu, select "Desktops" then select "New Desktop"

OBSERVED RESULT
The entire desktop session crashes - all windows disappear, there's a black screen for a few seconds, after which the session restarts as if new (including starting applications from the previous session).

EXPECTED RESULT
I'm not really sure what I expect to happen - maybe a new desktop with a default name added to the end of the virtual desktop list? Will the window operations menu close? will the active window be moved to the new desktop? I'm not sure, but I'm pretty sure I expect the session to not crash :-)

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.83.0
Qt Version: 5.15.3
Comment 1 Oded Arbel 2021-06-06 08:57:32 UTC 
I didn't get a Dr. Konqi dialog for this crash, but I found a crash file in /var/crash which may be relevant - but it is too large to attach (even after compressing) so I uploaded it to here: http://code.geek.co.il/dumps/2021-06-06-_usr_bin_kwin_wayland.1000.crash
Comment 2 Oded Arbel 2021-06-06 08:59:23 UTC 
After the session recovered, I notice that there is indeed a new virtual desktop with a default name ("Desktop " followed by a number that is one larger than the previous virtual desktop count).
Comment 3 Vlad Zahorodnii 2021-06-07 07:24:24 UTC 
iirc crash files can't be open on another computer. Can you please post the backtrace in text form here? you'll need to open the coredump file using gdb; or maybe it's possible to use coredumpctl.

The interesting part of the crash file is here:
