Unfortunately the backtrace is incomplete and missing debug symbols:

If this crash is reproducible in the latest Plasma version, could you please install debug symbols, reproduce it, and attach a new symbolicated backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports

Thanks!
