title: Embeded Matplotlib Graph into Tkinter crashes on Python 3.5
body: <p>While porting Python 2.7 script to Python 3.5, this code crashes in Windows Anaconda 2.4.1 (64-bit):</p>
  
  <pre><code>import tkinter as Tk
  import matplotlib.pyplot as plt
  from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
  
  root = Tk.Tk()
  
  fig = plt.figure()
  canvas = FigureCanvasTkAgg(fig, master=root)
  canvas.get_tk_widget().place(relx=0.02, rely=0.14, relheight=0.83, relwidth=0.96)
  
  Tk.mainloop()
  </code></pre>
  
  <p>The root cause is <code>get_tk_widget().place()</code> method. Windows Event View provides this info:</p>
