D-Bus library Issue with flight gear in SITL

Hi,
I am trying to use flightgear for sitl- as asked in the page:Setting up SITL on Linux — Dev documentation

But I am getting this error:

aditya@MATHWORKS-vEda3:~/myArduPilot/ardupilot/Tools/autotest$ fg_quad_view.sh
0.03 [WARN]:gui QStandardPaths: wrong permissions on runtime directory /run/user/1000/, 0755 instead of 0700
0.04 [ALRT]:aircraft Aircraft does not specify a minimum FG version: please add one at /sim/minimum-fg-version
Now checking for plug-in osgPlugins-3.6.5/osgdb_nvtt.so
0.61 [WARN]:general Enabling ATI/AMD viewport hack
dbus[755705]: arguments to dbus_connection_set_exit_on_disconnect() were incorrect, assertion “connection != NULL” failed in file …/…/…/dbus/dbus-connection.c line 3149.
This is normally a bug in some application using the D-Bus library.

D-Bus not built with -rdynamic so unable to print a backtrace
Aborted (core dumped)

Any clues on what is going wrong here?
