https://trac.bbpress.org/ticket/934

Basically if you have any template functions that depend on bb_get_forums_hierarchical() then you can’t have more than one of them on a page… so for example, any pages that show the hierarchical forums list and then also show bb_new_topic_forum_dropdown() will fail.

Diff to fix included in the ticket.
