No, its not a bug. its a feature! See the discussion in the recursive
generator thread below:

http://groups.google.com/group/comp.lang.python/browse_frm/thread/4c749ec4fc5447fb/36f2b915eba66eac?q=recursive+generator&rnum=1#36f2b915eba66eac

In my opinion, traversing recursive data structure is where generator
shine best. Alternative implementation using iterator is lot more
difficult and lot less elegant. Unfortunate the right now recursive
generator would carry a price tag of O(n^2) to the level of depth.
