The problem is not so much the length of the URI, but it is a bug in  
the validator.
The CSS validator, when called with check?uri=referer does a  
redirection to validator?uri=http://the/real/URI...

The Referer URI has to be escaped (URI-encoded) otherwise parameters  
in that URI will end up like

http://jigsaw.w3.org/css-validator/validator?uri=http...?foo=bar&quz=zog
here, quz=zog is interpreted as being parameters *for the validator*
whereas the redirect should go to
http://jigsaw.w3.org/css-validator/validator?uri=http...%3Ffoo%26bar% 
3Dquz%26zog

I fixed the bug in the dev version of the validator. There is a small  
technical issue  preventing me from updating the production instance,  
but that should be solved within a few days, too..


Thanks.
