This is a gdb backtrace of the process while its memory was steadily increasing. I'm not sure if that's useful, but I hope it is!

SUMMARY
This is unfortunately not easily reproducible, but the times I was able to trigger this was upon a clean boot. The bug happens upon clicking on this clickable URL being displayed inside of a program called TwitchDropsMiner.

STEPS TO REPRODUCE
1. Download this portable program that displays the clickable link: https://github.com/DevilXD/TwitchDropsMiner/releases/download/dev-build/Twitch.Drops.Miner.Linux.PyInstaller.zip
2. Extract the zip file and run the "TwitchDropsMiner" executable
3. Go to the "Help" tab
4. Under the "Useful links" section, click on the "See Twitch inventory" link

OBSERVED RESULT
Sometimes, after you click on that link a process named ktraderclient5 spawns and gets stuck using a lot of CPU and memory, indefinitely.

EXPECTED RESULT
Upon clicking the link I expect it to open on Firefox (my default web browser)
