Package: python2.3-pygame
Version: 1.7.1release-2
Severity: important
This fragment of code (extracted from solarwolf) caused pygame to hang
on my system:
import pygame, pygame.font
pygame.init()
pygame.font.init()
pygame.font.SysFont('sans', 16, italic=1)
To reproduce, make sure you have Bitstream Vera and don't have Arial and
Helvetica installed.
I traced the execution; pygame is getting in an endless loop after
incorrectly parsing fontconfig's fonts.cache-1 files. Trying to read
those files is of course a gross hack. The attached patch throws all
that code away and replaces it with a function that parses the output of
the fc-list command. Still ugly, but at least it works. (The proper way
of course is to use fontconfig directly, but there doesn't seem to be a
python module for that.)
