we are missing important information from your backtrace, can you install
the debug symbols?

konsole (20.12.2) using Qt 5.15.2

I would like to add that I've now installed the debug symbols for a full report.  Konsole crashes immediately on opening every single time under both xorg and wayland on my Intel Kaby Lake laptop w/ intel graphics:

Comment 5 eric 2021-04-22 01:00:55 UTC
Ok I have tried deleting my ~/.config/konsolerc and now konsole opens just fine.  
I believe the issue was my default konsole profile had the setting to "randomly adjust colors for each session" under Edit Color Scheme. 
If I create a new profile in konsole settings and use "randomly adjust colors" then set it as default it causes the same crash behavior.

Fix type of randomSeed parameter

It should be uint. I am not sure this fixes the mentioned bug, but it's
correct anyway, std::mt19937 and co. unsigned types; and we shouldn't mix
signed with unsigned.

Fix crash when using a color scheme with random colors

A new assert in GCC 11.1.0 std::piecewise_linear_distribution fails in
the case that the lower and upper boundaries are equal.  So, make sure
to not construct a std::piecewise_linear_distribution when minSaturation
equals maxSaturation and when minLightness equals maxLightness.
