    This should be closed as duplicate of bpo-22810. Tracker malfunctioning right now.

    On Windows 7, no problem on either 2.7.10 or 3.5.0b2 (running from Command Prompt so would see message is there were one).

    Unfortunately can't reproduce the issue in 2.7.6, 2.7.10+, 3.4.0, 3.4.3+, 3.5.0b2+, 3.6.0a0 with Tcl/Tk 8.6.1.

    The only output is:

    Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/lib-tk/tkFileDialog.py", line 125, in askopenfilename
    return Open(**options).show()
  File "/usr/lib/python2.7/lib-tk/tkCommonDialog.py", line 48, in show
    s = w.tk.call(self.command, *w._options(self.options))
_tkinter.TclError: can't invoke "grab" command: application has been destroyed

    I have not experienced this problem on windoze. The problem seem to have appeared when upgrading my operating system from Debian wheezy to jessie, I think with python going from 2.7.3 to 2.7.9. And I have a stomach feeling it is related to the environment. I have filed a bug report at debian too, or I am working on it.

    With the initial description I have been wanting to say that just opening the root window and closing it does not crash python. But open it, use askopenfilename and then close the root window lead to a crash.
