views in subpaths of other views show wrong breadcrumbs

hey there,

I noticed that if I create a view whose address is example.com/foo and another addressed at example.com/foo/bar (with matching breadcrumbs), the second one shows breadcrumbs from the first.

expected behaviour:
view: example.com/foo
breadcrumb: Home > foo

view: example.com/foo/bar
breadcrumb: Home > foo > bar

what happens:
view: example.com/foo
breadcrumb: Home > foo

view: example.com/foo/bar
breadcrumb: Home > foo

any ideas? thanks in advance.

cheers,
Luciano
