CSS Validator broken?

Hello,
I've just been shocked by the number of errors a previously validated
style sheet now throws up.  After a while I tried validating

P { font-size: 12pt; }
BLOCKQUOTE { font-size: larger }
EM { font-size: 150% }
EM { font-size: 1.5em }

using http://jigsaw.w3.org/css-validator/validator-text.html
(Normal report, no special profile, Medium: all)

and got 

     URI : file://localhost/TextArea 
     Line: 1 Context : P Invalid number : font-size 
          Unknown dimension : 12pt 
     Line: 3 Context : EM Invalid number : font-size 
          only 0 can be a length. You must put an unit after your number : 150 
     Line: 3 Context : EM 
          Parse Error - 150% } 
     Line: 4 Context : EM Invalid number : font-size 
          Unknown dimension : 1.5em 

Surely something's wrong here?

Phil
