Doesn't display anymore node which root is vocabulary

Hi,
Taxonomy_menu 4.5 used to show nodes that belong directly to the vocabulary, but they were a problem when looking at the taxonomy_menu/vid where there was a term id = vid (now fixed with current version).
But now, I can't see anymore my nodes which didn't belong to a precise term.

Hope I was clear.

Way to reproduce bug :
Create a vocabulary, create a story which belong to the root of this vocabulary (path [none]) and then browse directly taxonomy_menu/vid you should normally see this node, but you don't.

I would have a look tomorrow a little more in depth to code, bu I'm pretty sure the problem come from $tree = taxonomy_get_tree(arg(1)); that don't retrieve nodes associated to vid.
