plugin doesn't function properly when "Activity Stream" is set as home page

I've got our Buddypress installation set up default to the Activity Stream page as the home page (by setting Settings -> Reading -> Front page displays -> A static page -> Front page -> Activity Stream).

Unfortunately, BP Activity Plus doesn't function properly on that page when set up in this way - the link buttons don't appear in the activity entry pane and the posted thumbnails are full size.

It appears normally when on a member's profile page (and elsewhere) but, needless to say, not having it on the home page is a problem.

Any chance this is an easy fix?
