Two dashes in node title ("--") cause trackback comment tag to be closed

Any node with two dashes in the title, like below, causes the comment tag around the trackback in output to be closed, leaving the "actual" end of the comment code displaying as plain text.

Title: Your candidate -- ask your questions!

Code resulting:

<!--
<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:trackback="http://madskills.com/public/xml/rss/module/trackback/">
<rdf:Description rdf:about="http://www.reamp.org/gwscandidates" dc:identifier="http://www.reamp.org/gwscandidates" dc:title="Your Global Warming Solutions Working Group candidate -- ask your questions!" trackback:ping="http://www.reamp.org/trackback/3104" />
</rdf:RDF>
-->

the "-->" at the end displays to the visitor, a minor problem.

Probably the function that outputs the trackback should filter out any "--" that might close the comment tag.
