It seems that the fix in Cairo solves the "0a" problem of the original poster (embedded fonts), but there are also other "0a" problems which are not covered (other embedded binary data, like pictures or so).
So we can approve the Cairo fix to at least help the users who cannot print files with embedded fonts, but we need to get Cairo completely fixed to cover all "0a" cases.
