crash on sleep

I have experienced a few crashes when I put the computer to sleep and then when I resume from sleep by, for example, pressing a button on the keyboard

I have attached full gdb dumps with debug symbols.

This looks like a dup of https://bugs.kde.org/show_bug.cgi?id=442677

@David are you still able to reproduce the crash?
Comment 4 Pawel 2021-09-22 10:43:54 UTC 
there are 2 patches in 442677. Do I need to apply both to re-test this bug or one of the 2?

I can give it a try.
Comment 5 Zamundaaa 2021-09-22 13:20:38 UTC 
You only need the newer one. Or simply use the Plasma/5.23 branch directly.
Comment 6 Pawel 2021-09-23 09:23:19 UTC 
I have not experienced this crash since applying that patch. I will keep an eye out and report back should it re-occur.

many thanks!
