Thank you for the bug report! Unfortunately I can't reproduce the crash myself on current git master, and the backtrace is incomplete and missing debug symbols for the following lines that we need to figure out exactly what's going wrong. Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

I tried to create a reproducible example and realized that this ticket was wrong. xdg-desktop-portal-kde crashes because kwin stops, but kwin terminates with a SIGTERM signal - this is not a crash. Can you suggest how I can track down why kwin terminated?
