Another realisation: It appears that tools->showall is being ignored in the filter if the gconf key value /apps/gnome-system-tools/users/showall is being assigned to tool->showall correctly:
gnome-system-tools-2.20.0/src/users/groups-table.c::groups_model_filter():
return (tool->showall || (gid == 0 || (gid >= tool->minimum_gid && gid <= tool->maximum_gid) ) )
If it is set the filter ought to return 'true' regardless of minimum_gid when /apps/gnome-system-tools/users/showall is true.
