Problem using linkchecker in doucment containing <BASE> element

Hi 
   I ran the W3C linkchecker on one of my pages, and although the H1 tag
gave the correct URL, it actually checked the directory above the page,
which happened to be the <BASE> of the document - see:  
http://validator.w3.org/checklink?uri=http://www.ukoln.ac.uk/web-focus/e
vents/workshops/webmaster-2002/qa/
   Is this a bug?
   Thanks
   Brian
