Backtrace from coredumpctl gdb - bt

If you're not sure this is actually a bug, instead post about it at https://discuss.kde.org

If you're reporting a crash, attach a backtrace with debug symbols; see https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

SUMMARY
Sometimes when I wake up my two monitors from sleep, when I right click on the desktop of the second monitor (non-primary) to get the context menu, plasmashell crashes and then restarts.

STEPS TO REPRODUCE
1. Let the monitor sleep or sleep it with kscreen-doctor --dpms off
2. Wake the monitors from sleep
3. Right click on the desktop of the second monitor that is not the primary monitor

OBSERVED RESULT
The context menu doesn't appear and plasmashell crashes.

EXPECTED RESULT
We should get the context menu without crashing plasmashell.

Comment 1 Nate Graham 2024-06-14 16:10:51 UTC 
Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong:

> #10 0x00007b1140f67bb9 in ??? () at /usr/lib/libPlasmaQuick.so.6

Could you please install debug symbols 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!

Comment 3 Ziad 2024-06-14 17:22:12 UTC 
I have set up arch's debuginfod and ran plasmashell in gdb. I managed to crash it. I hope this 4679 lines backtrace with debug symbols is going to be helpful.
Comment 4 Nate Graham 2024-06-14 20:39:11 UTC 
This looks like something else. I don't see "plasmaquick" anywhere in that backtrace, and also it's not clear which thread crashed. In general we only need the crashing thread, not all of them.

Backtrace from coredumpctl gdb - bt with ALL debug Symbols

Backtrace from coredumpctl gdb - bt with ALL debug Symbols with Arch's debuginfod enabled as requested. It has 40 lines so I hope this one will be more useful.
Comment 6 Ziad 2024-06-15 16:09:49 UTC 
Sorry for the back and forth, this bug submission has really been a learning experience.
Comment 7 Nate Graham 2024-06-17 16:48:30 UTC 
This one also doesn't have plasmaquick in it, but it does look more like what I would expect for a right-click. So let's assume this is the correct backtrace and the original one was something else.
