Maybe someone could help me with the following problem.
When I navigate to an item via a tag, the tag does not show in the breadcrumb.  For example:

Home > Catalog > MyTag  

:: this displays the items with the tag 'MyTag'. If I click on an item then the breadcrumb is:

Home > Catalog > MyItem

:: so basically it doesn't show that i have navigated to 'MyItem' via 'MyTag'.  This kind of defeats the purpose of a breadcrumb.

Any ideas?  Thanks!
