Package: python-pyglet Version: 1.1.4.dfsg-3 Severity: important Tags: upstream patch
Dear Maintainer, pyglet in stretch causes a segmentation fault when using the font routines. This can be trivially reproduced: import pyglet pyglet.font.load("", 30) Segmentation fault This problem does not occur in jessie. I have tracked this down to the way that ctypes is being used to call the fontconfig library. Please find attached a patch which fixes this. This is probably important enough to consider a stable update once the fix is in unstable, as any application which calls pyglet.font.load in stretch will segmentation fault (e.g. psychopy as soon as a TextStim object is created). Thanks, Mark
