New crash information added by DrKonqi

DrKonqi auto-attaching complete backtrace.

This backtrace is amazing and has every debug symbol except for the ones we need! For example:

#36 0x000077c32fedb5a3 in ??? () at /usr/lib/qt6/plugins/plasma/applets/org.kde.plasma.private.systemtray.so

Could you please install debug symbols for Plasma and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.

Thanks again!

Is there a way to get the core file from Dr Konqi? It happened again, and just those symbols are missing information, again.

Just use `coredumpctl`, as the documentation says. It should prompt you to download the missing debug symbols.

coredumptctl didn't help. Still had question marks for that library. I think my install was scuffed; I went to kde-unstable to test beta2, and then went to testing for the release version, and had to do some package cleanup. I've upgraded to 6.0.2 in normal repos. We'll see if it happens again.

6.0.2 backtrace

It happened again (version 6.0.2-3). New backtrace added. No question marks this time!

There we go, much better! Thanks. Pasting inline for searchability:

To be clear, you're right-clicking on Steam's System Tray icon when this happens, right?

Yes. It doesn't always happen, to be clear.

I can also sometimes reproduce it

*** This bug has been marked as a duplicate of bug 484261 ***

*** Bug 488190 has been marked as a duplicate of this bug. ***

Un-marking as a duplicate of Bug 484261 since that was supposed to be fixed in Qt 6.7, but we're still getting crash reports from people not using Qt 6.7.

I haven't been able to reproduce this.

I haven't seen it either recently.

Operating System: Arch Linux 
KDE Plasma Version: 6.0.5
KDE Frameworks Version: 6.2.0
Qt Version: 6.7.1
Kernel Version: 6.9.2-arch1-1 (64-bit)
Graphics Platform: Wayland

Ok, let's call it fixed for now. We can re-open this if we get any reports from anyone using 6.1 or later.

*** Bug 498939 has been marked as a duplicate of this bug. ***

Got a report of the same crash (backtrace and all) from someone using Plasma 6.2.4; re-opening.

Worth adding, I suspect it has to do with connecting and disconnecting a second/third monitor.
Haven't narrowed it down, but I have a hardware A-B switch for the primary monitor so I suspect this happens after connecting one monitor back in and it becomes primary as it has higher priority.
This also used to happen in plasma 5 on debian bookworm, but I could never reproduce it reliably.
