Failed to parse HTML Head

In the above report, SC refused to parse the HTML Head section and instead 
returned an error. Following the link, it would appear that SC is now being 
much more strict. So, I increased my screen resolution to 2048 x 1536 and 
maximised the message source window so that each line would be copied to 
the clipboard without breaks. I checked the textarea in the reporting form 
to ensure that no extra line breaks occurred. SC still returned the error 
and refused to parse the HTML section.

Looking at the source, I suspect that it's tripping up on the following 
lines:

------=_NextPart_001_0001_291C5BDC.A05E6DC5
Content-Type: text/html;
    charset="iso-8859-1"

Now, that break is spammy's doing, not mine. So, if this is what is 
tripping up the SC parser then spammy has found yet another way to 
circumvent SC.
