CSS Validator broken?

CSS Validator is giving me a rather strange error.

I'm checking a document that validates as XHTML 1.0 Transitional:

    http://validator.w3.org/check?uri=http://www.openmikes.org/listings/

but when I try and run the same page through jigsaw:


http://jigsaw.w3.org/css-validator/validator?uri=http://www.openmikes.org/li
stings/

I see the following error:

    Please, validate your XML document first!
    Line 86
    Column 7
    The element type "span" must be terminated by the matching end-tag "".

Am I missing something in my document, or is there a problem with the
validator?
