The below code work perfectly when I run it as a console application

import gtk.gdk
import time

w = gtk.gdk.get_default_root_window()
sz = w.get_size()
print "The size of the window is %d x %d" % sz
pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB,False,8,sz[0],sz[1])
pb = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,sz[0],sz[1])

ts = time.time()
filename = "screenshot"
filename += str(ts)
filename += ".png"

if (pb != None):
    print "Screenshot saved to "+filename
    print "Unable to get the screenshot." 

But now I when I used it in a ubuntu application (using the quickly and glade) it is giving me error messages

 WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-O1o56xxlHA: Connection refused
/usr/lib/python2.7/dist-packages/gobject/constants.py:24: Warning: g_boxed_type_register_static: assertion `g_type_from_name (name) == 0' failed

How can I improve this code to work in GUI based application

EDIT What I have done to change the code

from gi.repository import Gdk, GdkX11, Gtk

        w = Gdk.get_default_root_window()
        geo = w.get_geometry()
        pb = GdkPixbuf.Pixbuf.new(GdkPixbuf.Colorspace.RGB,False,8,geo[2],geo[3])
        pb = pb.gdk_pixbuf_get_from_window(w,0,0,geo[2],geo[3])       
        pixbuf = pb.get_from_drawable(w,w.get_colormap(),0,0,0,0,geo[2],geo[3])        
        print "The size of the window is %d x %d" % sz
        pix = GdkPixbuf.Pixbuf.gdk_pixbuf_get_from_window(root_window, 0, 0, 500, 500)
        pix = GdkPixbuf.gdk_pixbuf_get_from_window(window,0,0,500,500);

       ts = time.time()
       filename = "screenshot"
       filename += str(ts)
       filename += ".png"

       if (pix != None):
           print "Screenshot saved to "+filename
           print "Unable to get the screenshot." 

But still it is giving me error

(0, 0, 1366, 768)

The correct way to take an Screenshot using PyGobject (the Gtk version used by Quickly) is:

from gi.repository import Gdk

window = Gdk.get_default_root_window()
x, y, width, height = window.get_geometry()

print("The size of the root window is {} x {}".format(width, height))

# get_from_drawable() was deprecated. See:
# https://developer.gnome.org/gtk3/stable/ch24s02.html#id-
pb = Gdk.pixbuf_get_from_window(window, x, y, width, height)

if pb:
    pb.savev("screenshot.png", "png", (), ())
    print("Screenshot saved to screenshot.png.")
    print("Unable to get the screenshot.")

The first version you posted is for the older PyGtk. So it works on console because it only loads PyGtk. In Quickly apps, PyGobject is loaded, and you cannot load both. You got stuck looking for get_from_drawable(), see section "GdkDrawable is gone":
