Breadcrumbs for a view page with arguments
I believe when you are creating a view that has an argument you can the opportunity to set a breadcrumb from within views itself.

Substitutions will also be available based on the arguments present.

For example, if you view is

/blogs/2011


Where blogs is the path to the page, and 2011 is the argument, you could set the breadcrumb of the page with the argument to be:

%1


This would leave breadcrumbs that would look like:

Blogs &gt; 2011
