json-glib problem

[Aldrich Niklaus <aldrichnjit gmail com>]

I want to us json-glib to parse a json file ,and I wrote a demo like this.

#include <stdio.h>

#include <stdlib.h>

#include <glib.h>

#include <glib-object.h>

#include <json-glib/json-glib.h>

int main(int argc,char **argv)

    {

        JsonParser *parser;

        GError *error;

        g_type_init();

        parser = json_parser_new();

        json_parser_load_from_file(parser,"info.json",&error);

        if(error)

            {

                g_print("error is %s\n",error->message);

                g_error_free(error);

                g_object_unref(parser);

                return EXIT_FAILURE;

            }

        JsonNode *root;

        root = json_parser_get_root(parser);

        if(JSON_NODE_HOLDS_ARRAY(root))

            {

                puts("hold array\n");

                JsonArray *array;

                array = json_node_get_array(root);

                g_print("the length of the array is %d\n",json_array_get_length(array));

                root = json_array_get_element(array,0);

                if(JSON_NODE_HOLDS_OBJECT(root))

                    {

                        JsonObject *newobj;

                        newobj = json_node_get_object(root);

                    }

        return EXIT_SUCCESS;

            }

    }

and the info.json file is here.

but when I compile the demo,I got a segment fault,I do not know what`s wrong with my demo program.
