python - cannot associate image to tkinter label

I am trying to display an image to a tkinter GUI using tkinter.Label() widget. The procedure seems simple and straightforward, but this code doesn't work!

code:

import Tkinter as tk
import Image, ImageTk, sys

filename = 'AP_icon.gif'
im = Image.open(filename) # Image is loaded, because the im.show() works

tkim = ImageTk.PhotoImage(im)

root = tk.Tk()

label = tk.Label(root, image = tkim) # Here is the core problem (see text for explanation)
label.image = tkim # This is where we should keep the reference, right?
label.grid (row = 0, column = 0)

tk.Button(root, text = 'quit', command = lambda: sys.exit()).grid(row = 1, column = 1)
root.mainloop()

When we execute this code, it doesn't compile, giving an error:

TclError: image "pyimage9" doesn't exist

When I define label without its parent root, No compilation error occurs, but the GUI does not display any image!

Can anyone identify what could be the issue?

This problem happens when we attempt to run the above code in Ipython. And it can be solved by changing the line

root = tk.Tk() to

root = tk.Toplevel()
