Copyright text replaces hrefs

Hi everyone!

I was adding the following Copyright text in the showcase Settings:

<img alt="Creative Commons License" style="border-width:0" src="http://i.creativecommons.org/l/by-nc-nd/2.5/pt/88x31.png"/>
<span xmlns:dc="http://purl.org/dc/elements/1.1/" property="dc:title" target="_blank" href="http://purl.org/dc/dcmitype/Text" rel="dc:type">The Rabbit Way</span> by Bruno Coelho is licensed under a Creative Commons Atribuição-Uso Não-Comercial-Vedada a Criação de Obras Derivadas 2.5 Portugal License.
Based on a work at TheRabbitWay.com.

However in every link the generated html adds \" after href=" breaking the html. Example:
<img src="\"http://i.creativecommons.org/l/by-nc-nd/2.5/pt/88x31.png\"/" style="" license\="" commons="" alt="\"Creative">

How can it be fixed?

Thank you,
Bruno Coelho
