I'm afraid Plasma 5.17.5 is no longer supported. Supported versions are 5.18, which is an LTS version, and the latest version, which is currently 5.20.

Are you able to upgrade and reproduce this with a later version?

Hi Nate,

Sorry, this is happening on Debian bullseye not on the Debian buster.

To answer your question, I am experiencing the problem since I upgraded the
system there was no problem before the upgrade.

Kind regards,
Laszlo

New crash information added by DrKonqi

systemsettings5 (5.17.5) using Qt 5.15.1

- What I was doing when the application crashed:
I opened systems settings to view the window decoration settings.

I did that while running openbox as Window manager, because previously kwin crashed.
For the kwin crash I was not able to create a backtrace, because the kwin-crash somehow affected drkonqi in such a way that I couldn't finish the report.

Comment 7 Nate Graham 2020-11-11 17:20:02 UTC
Are people only seeing this in 5.17.5, or is it reproducible with a newer version of Plasma?

I don't have access to newer version.

Comment 9 Nate Graham 2020-11-11 19:28:11 UTC
That's a shame. Plasma 5.17.5 is no longer supported, and I wish discrete release distros would use LTS versions or else use a fast enough release schedule that locking to a fixed version doesn't result in users being a year or more out of date.

What can I do to fix this? I'm aware if the pain.

Use a different distro or switch to a different Debian repo/version that has more recent versions of KDE software or a faster release cycle.

KDE has no input over distro scheduling choices, but we can complain about them. :)

Well, I got an update to kwin (version 4:5.19.5:something) today via apt and that solved the problem. Plasma version is still 5.17.5 btw
