sending a{sv} is crashing

[Raghavendra. S]

 Hi All,

  I am trying to call ConnectService API defined in connman (open source
connection manager daemon). Connman has defined ConnectService with "a{sv}"
signature.

  When I tried to form and send message using below code, code is crashing
with signal 11. Please let me know whats the issue in below code.


#include <stdio.h>
#include <errno.h>
#include <stdlib.h>
#include <string.h>
#include <stdbool.h>
#include <glib.h>
#include <dbus/dbus-glib.h>
#include <dbus/dbus.h>
#include <sys/types.h>
#include <sys/stat.h>
