Hello Jack Barns, I am not involved in packaging spacefm, but just tried to reproduce the issue. "Unfortunately" for my test it did not freeze.
If you still can reproduce it, maybe you can execute following command while a single spacefm process is in the system and hangs: script -a "spacefm-gdb_$(date +%Y-%m-%d_%H-%M-%S).txt" -c "ps -C spacefm -mo %cpu,pid,tid,user,args; gdb -q --pid $(pidof spacefm) -ex 'set width 0' -ex 'set pagination off' -ex 'thread apply all bt full' -ex 'detach' -ex 'quit'" This should generate a file spacefm-gdb*.txt which could be forwarded to this bug. Even better if the dbgsym packages could be installed before, like described in [1]. spacefm-dbgsym libgtk2.0-0-dbgsym libglib2.0-0-dbgsym Kind regards, Bernhard [1] https://wiki.debian.org/HowToGetABacktrace#Installing_the_debugging_symbols
