-- Information about the crash:
Hi,
I've had this maybe every second time I resume from Hibernate in Plasma 6.5.5. At first I thought it was Bug 506642, but now I'm not so sure - there's no KConfigIni in the callstack. Apologies if it's a dupe though
Many thanks,
Andrew

The crash can be reproduced sometimes.

I think it's the same one, the cause of the crash is similar, even if the stack isn't exactly same.

Thanks!
