5.12.2

Comment 3 Nate Graham 2021-02-23 06:19:57 UTC

Unfortunately the backtrace is missing some debug symbols and does not implicate any KDE code in its incomplete form. I don't think there's any way we'll be able to debug it in its current state. :( Are you able to reproduce this crash with Plasma 5.21?
