SourceForge.net - XHTML - where is error - different opinions :(

I found SourceForge.net badly acts in Opera 8.5x

I checked it in validators and found different results:
http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fsourceforge.net%2F&usermedium=all
~~~~
Target: http://sourceforge.net/
Please, validate your XML document first!
Line 143   Column 26
Element type "a" must be followed by either attribute specifications, 
">" or "/>".

http://validator.w3.org/check?uri=http%3A%2F%2Fsourceforge.net%2F
This validator also displays a lot of XML errors: one at line 16, a lot 
at line 176 and more below. But it does not display line 143 as 
erroneous nor does jigsaw display line 16 as wrong.

Strangely two official validators foudn different errors in same XML 
document :(
