Which tk? Did you ever activate Debugger in the session (known problem, see bpo-15347)? Can you reproduce this with a series of step you can post? How were you shutting down (I have had problems with 'Close Windows on a Windows Taskbar icon right-click menu)?

[ned-deily]

From the traceback, it does appear that the debugger was in use. Since there's not much else to go on here, I suggest closing this as a duplicate of bpo-15347.

I added a note to bpo-21339 about the traceback here.
