Comment:

 Sorry to bring bad news, but a trial sage-5.5.beta1 caused a Segmentation
 Fault in {{{sage/schemes/elliptic_curves/ell_number_field.py}}} on OS X
 10.4 PPC.  Removing #715 and #11521 made the problem go away.  This really
 feels like a déjà vu, but I'm afraid I need to remove the patch from
 sage-5.5.beta0.
