The problem is that new_graf might not inject dir nodes even if
no_local_dirs_par is positive, which break the synchronization between the open
dir nodes and no_local_dirs_par.
Like at the start of boxes, no_local_dirs_par should be reset, but then if dir
nodes are injected it should be incremented.
I attached a fix.
thanks,
