Just as with all GLib application you can run it with
G_DEBUG=fatal-criticals to abort() on those, so that you can
investigate them in gdb. Most often the backtrace also has some hint
where you are in the Python code at that point, but that requires
debugging symbols to be installed. You can also run the program
through pythonX.Y-dbg, which should help as well.
