Hello Russel, thanks for the fast answer, unfortunately the backtrace is not yet enough expressive. Maybe you could also install the following debug symbol packages? libqt5qml5-dbgsym libqt5core5a-dbgsym libqt5widgets5-dbgsym libqt5gui5-dbgsym kwin-common-dbgsym kwin-x11-dbgsym These are located in a separate debug symbol repository, which has to be enabled first and is described here: https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols Kind regards, Bernhard
