python - SystemError: <built-in function destroyAllWindows> returned NULL without setting an error

Question

I have created a simple python program in which i have used opencv to display a image and tkinter to show some information about the image in tabular format with the help of treeview.

I have binded the arrow key of right to close the tkinter windows as well as the opencv window but when i pressed the key the tkinter window closes but the opencv window does not and shows this message:

SystemError: <built-in function destroyAllWindows> returned NULL without setting an error

I can't show you the code because its too long . Does anybody know how to solve this error message i searched through the internet and looks like this error message appears in imread function of opencv but in my case when i use cv2.destroyAllWindows() then it shows message and there is no question like this in stack overflow.
