found it, should be fixed with commit 849862c332f6. thanks!
the noatime option wasnt a very good idea in the first place. it will make dumps slow because the recursive walk uses the block dirty flag to guide its recursive descend into the tree as a optimization. without parent directories automatically being dirtied by walks, we have to traverse all directories to find the modified files.
