Summary: wrong multiplicities for a simple polynomial

Initial Comment:
solve produces correct solutions, but wrong multiplicities:
(%i1) solve((z^2-1/%e)^3=0,z);
				  1	        1
(%o1) 		        [z = - --------, z = --------]
			       sqrt(%e)	     sqrt(%e)
(%i2) multiplicities;
(%o2) 				    [1, 1]
(%i3)
