emacs-w3 error in css

[Peter Rayner <peter.rayner@xxxxxxxxxxx>]

I'm getting the following error trying to access an on-line journal
page

Now a bit of glaring at this suggests the problem is the following
span.c4 {color: #FF0000\"}\n
which looks like a malformed css declaration.  
The question is whether it's coming from my end, i.e some kind of
default  or whether I should complain to the page admin.  
Looking at the source of the page I don't see any declaration that
looks like this.  

I'm using emacs, emacspeak and w3 from cvs.

Anyone understand emacs-w3 stylesheet handling well enough to know
where the arguments for css-parse are coming from?
thanks in advance
Peter
