Breadcrumb doesn't follow taxonomy structure

I defined taxonomy "Main Site Sections" with a number of terms, such as "About Us" below it. If I set up a term as a menu item, clicking the menu item will list the nodes and their teasers associated with that term, and clicking the read more link of course gives the whole node content, however neither with the list of nodes or the full content of the node is there anything in the breadcrumb trail other than "Home:: ".

I've searched the site for related problems and found several including http://drupal.org/node/220803 , which deals with a problem associated with the Taxonomy menu module, which I've disabled on my site. In any case, this seems to be a widespread problem with either "Array::Array::" or "Home::" being the only display in the breadcrumb trail. Hopefully this will be addressed soon as the breadcrumb trail is useless otherwise.
