I'm trying to test Tkinter and Pillow on MINGW64 but I get a Segmentation fault.
The following minimal example works and shows an empty window:
import tkinter
top = tkinter.Tk()
# Code to add widgets will go here...
top.mainloop()
This one produces a segfault:
# tkinter_pillow.py
from tkinter import Tk, Frame, BOTH
from PIL import Image, ImageTk
class Example(Frame):
def __init__(self):
super().__init__()
self.master.title("High Tatras")
self.pack(fill=BOTH, expand=1)
self.img = Image.open("test.jpg")
self.tatras = ImageTk.PhotoImage(self.img)
root = Tk()
ex = Example()
root.mainloop()It should show nothing, because it's incomplete, but it should not crash.
I tried the following example too: https://raw.githubusercontent.com/python-pillow/Pillow/3.0.x/Scripts/viewer.py. It also produces a Segmentation fault.
