I don't see why you think that this is a bug.  You asked for only two 
factors instead of full factorization.

Also, this has been said several times before, yet you take no heed: do 
NOT reply to and old message when you intend to start a new discussion. 
   This masks the subject of the old thread, and is very annoying for 
those of us who use threaded newsreaders.
