PDF Woes -- Need example

[Julian Field]

I have found the problem, but can't figure out how to correct it. The docs 
in the MIME-tools say that the CRLF sequences are fuzzed on output, which 
is the problem. But I cannot find the actual code that does this. For 7bit 
decoding it is dead easy to find, but that code is not used by the 
quoted-printable handler and I can't find any others.

:-(
