In customer/home.tpl, replace this:

{include file="location.tpl"}

with this:

{if $main eq "catalog" and $current_category.category eq ""}
{elseif $main eq "product" or $main eq "catalog"}{include file="location.tpl"}{/if}

That will cause the breadcrumbs to only show up on the product and category pages.
