The parts that use Gio for monitoring in mate-system-monitor are located
in prettytable.cpp, where it monitors its apps-cache, and in procman-app.cpp,
where it monitors mounts and somehow uses it to process a commandline; that's
also the place it crashes (after complaining about the missing monitor
facility):

ts(~) env LD_LIBRARY_PATH=/usr/gcc/10/lib dbx `which mate-system-monitor`
For information about new features see `help changes'
To remove this message, put `dbxenv suppress_startup_message 7.7' in your .dbxrc
