Issue18686 is reproducible to me. Here is a script based on issue18686 example. Run it and open the "File" menu.

$ python3 issue18686.py 
.#3069298188.#3069298188#3069298252
Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python3.5/tkinter/__init__.py", line 1553, in __call__
    return self.func(*args)
  File "issue18686.py", line 24, in entry_focus_lost
    widget_with_focus = self.focus_get()
  File "/usr/lib/python3.5/tkinter/__init__.py", line 550, in focus_get
    return self._nametowidget(name)
  File "/usr/lib/python3.5/tkinter/__init__.py", line 1204, in nametowidget
    w = w.children[n]
KeyError: '#3069298188'

But my patch doesn't help in case of tearoff menu. Detach the "File" menu and hover a mouse on its item.

$ ./python issue18686.py 
.#`menu.#`menu#`menu
.`menu.`menu
.tearoff1
