Reported using DrKonqi

Would you be able to provide the backtrace with debug symbols? It would really help us understand what's going on.
Comment 2 Cristiano Guadagnino 2020-03-27 23:04:50 UTC 
I tried two times to recreate the crash: I was able to both times, but DrKonqi did not start in both cases.
Without DrKonqi I don't know how to generate the backtrace with debug symbols.
I have the coredumps though, are they useful?

Here's some documentation on how to get the debug symbols.

Hope this helps.
Comment 4 Cristiano Guadagnino 2020-05-20 07:35:39 UTC 
I am now using Discover 5.18.5.
With this release, I am unable to reproduce the crash.
