At first let me admit, I'm not a programmer, although I have a lot of expierence in tweaking small bits of php here and there. Also I'm not very familiar with Magento's ways of coding.
I have this client who wants to add the manufacturer's brandname to the breadcrumb with a link to the brandname in it. We're using layered navigation that's where I got the link from.
The output I get is Home / Categoryname / productname of <A href="http://linktobrand.html">Brandname</A> Here in which the html doesn't get rendered because of the breadcrumbs block being echoed with the function toHtml().
