hey,

i boot kde neon user edition (current version) from iso.

the very first thing i do is right-click on the arrow for hidden symbols in the system tray, then select 'System Tray Settings', then select 'Entries', choose 'Always show all entries', and click 'OK'.

then plasma crashes. since no debug symbols are installed the crash reporting assistant cannot provide useful information, and installing debug symbols won't help either.

greetings.
