>>> tk = Tk()
>>> t = Text()
>>> t.pack()
>>> def printBbox():
...    print 'bbox returned: ', t.bbox(INSERT)
...
>>> b = Button(text="BBOX", command = printBbox)
>>> b.pack()
>>> tk.mainloop()
bbox returned:  (3, 3, 480, 13)
bbox returned:  (61, 3, 6, 13)
bbox returned:  (92, 29, 6, 13)
bbox returned:  (260, 3, 6, 13)


Seems to work OK for me.
