Active trails for posts belonging to an Organic Group

Hello,

I have several nodes belonging to an Organic Group and I'd like menu trailing and breadcrumbs reflecting this condition.

So imagine node 1 belongs to group 1. The expected behaviour should be that when visiting group 1 menu trails and breadcrumbs work (in fact they do) and when visiting node 1 menu and breadcrumbs should display "Home > Group 1>", which doesn't work.

At admin/build/menu/trails I made sure to check "Use group's menu item for posts" but it doesn't work (see attached screenshot to see my configuration options).

Am I missing something?

Thank you
