Odd return from Xenu

I am suddenly getting the following entry when I use Xenu to check my links.

http://www.masterpage.com.pl/enr/health/swine-flu-could-reduce-homeless-population/trackback/ no info to return

My robots.txt file was changed for me so I think it might be related to that.

But then it might not.

If it might be robots.txt, can someone give me a line to put in it to rid me of this return?

If not, where should I look?

Thank you.
