Once you have destroyed a widget you can no longer access its data:

>>> import tkinter as tk
>>> root = tk.Tk()
>>> text = tk.Text(root)
>>> text.pack()
>>> text.get("1.0", "end")
'\n'
>>> text.destroy()
>>> text.get("1.0", "end")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.3/tkinter/__init__.py", line 3107, in get
    return self.tk.call(self._w, 'get', index1, index2)
_tkinter.TclError: invalid command name ".140692133333008"
