Breadcrumbs Incorrect

Hi There,

I have a theme which shows a breadcrumb for the current page. When looking at Products in MarketPress the breadcrumb for a product is malformed. In shows as a child of itself. As an example, lets say I add a product "New Product"

the breadcrumb will show

"home > New Product > New Product"

when it should be

"home -> store -> NewProduct" or something like that.

Is this a known issue?

Thanks

Sam
