Comment 1 Nate Graham 2022-05-18 15:46:20 UTC 
If something crashed, we need a backtrace of it so we can figure out what's going on. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Can you please attach one? Thanks!

The problem is that every time discover crashes I get no backtrace. That sentence you see in the report is not mine, is from the bug report wizard in fact.
I don't know why, it simply doesn't create it. It does with other KDE apps...
anyway, here is the whole journalctl portion showing the crash. Better than nothing I suppose :)

You may be able to get it using the `coredumpctl` utility. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl

I've tried, but no trace for Discover unfortunately. Maybe the next time it crashes (I know it will), I'll try sending the bug report *before* closing the app. Who knows, maybe..

Ok, thanks. Let us know!
