Hello Pere Nubiola Radigales, I just saw this report without being involved in packaging freecad. And tried to reproduce the issue but failed.
Is it possible to save it into a file just before it crashes? Can the crash be reproduced by starting from that file? Otherwise you could install the package gdb and run freecad with following command line and forward the created file to this bug? script -c "gdb -q -ex 'set width 0' -ex 'set pagination off' -ex 'run' -ex 'display/i $pc' -ex 'bt' -ex 'info reg' -ex 'bt full' -ex 'detach' -ex 'quit' --args freecad" -a gdb_freecad_$(date +%Y-%m-%d_%H-%M-%S).txt Kind regards, Bernhard
