error: couldn't parse head

This is my first post, and I'm a spamcop newbie, so I hope this is posted 
in the correct group.

In posting the following spam to spamcop today:

http://www.spamcop.net/sc?id=z813081185zd334b68a2fec1233180387e3a14cac64z

I noted the error message "error: couldn't parse head" in the report and 
read the associated FAQ file. The FAQ indicates that the error was 
probably  that the "Content-type" header is not indented when carried 
over to a second line. The FAQ further insists that I introduced the 
error, but it appears to me to be in the original message.

My reporting method is to preview all messages with an old version of 
MailWasher (version 1.32), from which I copy and paste the offending 
message into spamcop and then delete the message without it even being 
picked up by my mail reader (Thunderbird). This method has worked 
flawlessly for several weeks/months, now, so I can't see any error on my 
part. I even cancelled the first report and resubmitted the offending 
message--with the same result.

So, I guess my point is to question the certainty of the FAQ entry or to 
determine if, in fact, I really did something to cause the error.

Thanks for any responses.
