To wstein and mhansen: The methods _shortest_paths(self) and _multiple_of_degree_of_isogeny_to_optimal_curve(self) in ell_rational_field come with the warning
The result is *not* provably correct, in the sense that when the numbers are huge isogenies could be missed because of precision issues. which is completely unnecessary *if* the parameter algorithm='mwrank' is *not* used in computing the isogeny class, since the default is to use the native Sage algorithm which does not have any such issues. (And has been in Sage since late 2009.) Was there a reason for using algorithm='mwrank' ? If not, that can be deleted and the warning removed.
