We're seeing this bug in Cairo 1.8.8 on OSX 10.5.8. (Specifically, it's the
1.8.8-2 package from fink.) A workaround (in Python) seems to be to call
ctx.select_font_face("sans-serif").

This script will tickle this bug; the commented-out line will un-tickle it.

import cairo
s = cairo.ImageSurface(cairo.FORMAT_RGB24, 300, 300)
ctx = cairo.Context(s)
# This line makes the problem go away
#ctx.select_font_face('sans-serif')
while True:
    txt = "hi!"
    x, y = (140, 140)
    ctx.save()
    try:
        ctx.text_path(txt)
        ctx.fill()
    finally:
        ctx.restore()
