I noticed some crashes with arc's too, some time ago, and couldn't 
reproduce them in c, it were really random crashes. And when i tried 
running the script from c(to use the MS debugger) it didn't crash, so I 
have no idea what the problem is. But what os etc are you using? Btw, I 
can't make it crash now, the attached code seems to work fine, can you 
try to run it, or send me some code that does crash.

import cairo
from math import pi

file = open("pycairoarcbug.png", "wb")

width, height = 400, 400
ctx = cairo.Context()
surface = cairo.png_surface_create(file, cairo.FORMAT_ARGB32, width, height)
ctx.arc(100, 100, 50, 5*pi/8, pi/8)
