Python / Script crashes on exit (sf.RenderWindow, sf.Texture)

I think I've found a bug in (py)SFML or Python 3.3.
When I run this code (it looks strange, but this is what remained after removing everything that didn't cause the crash):

import sfml as sf

window = sf.RenderWindow(sf.VideoMode(640, 480), 'test')

texture = sf.Texture.from_file('map.png')

window.close()
print('test')

the whole script executes, prints 'test' and then Windows shows a window saying that python.exe has stopped working. However, it doesn't crash in the IDLE python shell, only when I run the script directly.

Deleting the texture before the window is closed fixes everything:

import sfml as sf

window = sf.RenderWindow(sf.VideoMode(640, 480), 'test')

texture = sf.Texture.from_file('map.png')

del texture

window.close()

Looks like the crash is caused by the texture not being deleted before the window is closed. 

And this code:

import sfml as sf

window = sf.RenderWindow(sf.VideoMode(640, 480), 'test')

texture = sf.Texture.from_file('map.png')

window.close()
print('test1')
del texture
print('test2')

prints 'test1' and crashes like the first snippet, but unlike the first one it doesn't run fine in IDLE (it enters an infinite loop after print('test1')).
