Hello Saša Janiška, thanks for your fast response. Maybe you could also install following debug symbol packages:
libpixman-1-0-dbgsym libcairo2-dbgsym libchamplain-0.12-0-dbgsym libffi6-dbg libgjs0g-dbgsym libglib2.0-0-dbgsym libgtk-3-0-dbgsym gjs-dbgsym (and if size does not matter: libmozjs-60-0-dbgsym) And send another output of journalctl, that way the function names for each frame will be visible. These debug symbol packages are in a separate repository, details described here: https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols Did you receive this crash always calculating the same route? Does it also crash if you calculate a route between some other random locations? Kind regards, Bernhard
