Any chance this is still happening for yo in Plasma 5.19--or even better in the upcoming Plasma 5.20 (released tomorrow)?

Can you please install debug packages for kwin and submit a new backtrace with debug symbols?
Comment 7 Wolfgang Reh 2020-10-28 19:45:22 UTC
Hi,

where do I get these debug packages from? When I check with dnf I can
see a kwn-devel package, but no kwin-debug package.

I don't use Fedora, so I can't really help you with that, but quick duckduckgo'ing shows that you need to run `sudo dnf debuginfo-install -y <pkg>` where <pkg> is the name of kwin package

Comment 13 Nate Graham 2021-05-26 17:57:51 UTC
Still cannot reproduce. Any chance you could see if it's fixed in Plasma 5.21?
Comment 14 Wolfgang Reh 2021-09-21 18:10:37 UTC
Can't reproduce the bug with version:
Operating System: Fedora 34
KDE Plasma Version: 5.22.4
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.2
Kernel Version: 5.13.16-200.fc34.x86_64 (64-bit)
Graphics Platform: X11

But still the first virtual desktop has the same name in the system settings as the second one. But only in the system settings, during mouse-over in the status-bar the correct name is displayed.
Comment 15 Nate Graham 2021-10-18 02:05:19 UTC
*** Bug 443518 has been marked as a duplicate of this bug. ***
Comment 16 ratijas 2022-07-11 09:38:18 UTC
Can't reproduce / ain't getting duplicated desktops. New added desktops are named simply "New Desktop" for me, but it doesn't cause any troubles when removing them.

Operating System: Arch Linux
KDE: git master
Qt Version: 5.15.5
Kernel Version: 5.18.10-arch1-1 (64-bit)
Graphics Platform: X11
Comment 17 Szőts Ákos 2022-08-30 20:16:36 UTC
I tried to reproduce it. Now, what happens is, instead of a crash when I click Apply, the whole desktop is rendered unusable by kwin_x11 which starts spinning X11 and doesn't repaint windows anymore.

In another terminal (without X11) I could attach KWin to GDB and I saw the following:
