Breadcrumb home link, itemid=101 problem

[randomdev]

If I am in a category and click the breadcrumbs home link which is
http://www.domain.com/index.php?option=com_virtuemart&view=virtuemart&Itemid=101

Then I try to click on a featured product to view its details it gives a link like this
http://www.domain.com/index.php?option=com_virtuemart&view=productdetails&virtuemart_product_id=51&virtuemart_category_id=144&Itemid=101

Which just goes back to the homepage instead of showing the items details?

I dont have any problem clicking on the home menu button then viewing a products details (these links have no itemid appended), it is just a problem with the home breadcrumbs link.
