Package: python-pygame
Version: 1.7.1release-4.1+b1sam1
Severity: important
The attached python code does not seem to work. If I patch pygame with
the attached patch, it is revealed that the call to
PyString_AsStringAndSize in image_fromstring is corrupting the value of
h, causing the image size sanity check later in the code to fail!
$ ./pyg1.py
h = 192
h = 0
Traceback (most recent call last):
File "./pyg1.py", line 7, in <module>
i = pygame.image.fromstring (str (s.get_data ()), (256, 192), 'RGBA')
ValueError: String length does not equal format and resolution size
